Cellular Respiration
Cellular Respiration is the series of metabolic reactions that takes place in a cell that harvests chemical energy. The energy is converted from the stored chemical energy in molecules to the stored energy in ATP.
635 Questions
Do humans carry both cellular respiration and photosynthesis?
No, humans do not carry out photosynthesis. Instead, humans rely on cellular respiration to convert nutrients into energy. Photosynthesis is a process unique to plants, algae, and some bacteria, where they convert sunlight into energy.
What is the end product of each step of cellular respiration?
Glycolysis: 2 pyruvates, 4 ATP (net gain of 2), 2 NADH
Krebs Cycle: products per glucose molecule: 4 CO2, 6 NADH, 2ATP, 2FADH2
Electron Transport Chain: on average, each NADH will produce 3 ATP, and each FADh2 will produce 2 ATp. Water is also produced...
10 NADH= 30 ATP, 2FADH2= 4 ATP (plus 2 ATP from glycolysis and 2 ATP from Kreb's Cycle) total of 38.
One entire round of cellular respiration produces (at the most) 38 ATP.
hope this helps!
What happens to electrons during cellular respiration?
During cellular respiration, electrons are transferred along the electron transport chain, releasing energy at each step. These electrons ultimately combine with oxygen to form water, facilitating the production of ATP through oxidative phosphorylation.
Components of the chemical equation for cellular respiration?
After the three steps in cellular respiration glucose and oxygen are turned into carbon dioxide, water, and energy in the following equation:
C6H12O6 + 6O2 --> 6CO2 + 6H2O + energy
This energy comes in the form of ATP an energy rich molecue i.e. adenosine triphosphate
How do plants conduct respiration and photosynthesis?
Plants conduct respiration by breaking down glucose to release energy for growth and metabolic processes. This process occurs in the mitochondria of plant cells. On the other hand, photosynthesis takes place in the chloroplasts of plant cells where light energy is used to convert carbon dioxide and water into glucose and oxygen.
The meaning of respiration and photosynthesis?
Respiration is the process in which cells break down glucose to release energy, usually in the form of ATP, while using oxygen and producing carbon dioxide as a byproduct. Photosynthesis is the process in which plants use sunlight to convert carbon dioxide and water into glucose, storing energy in the form of carbohydrates and releasing oxygen as a byproduct.
When is carbon dioxide released in cellular respiration?
In anaerobic respiration CO2 is release in fermentation (in cytoplasm) but never during glycolysis. Also. It isnot formed during lactic acid fermentation. Only 2CO2 are formed per glucose molecule in fermentation.
In aerobic respiration, total 6Co2 molecules are generated per glucose molecule. 2Co2 during transition reaction i.e. during oxidative decarboxylation of pyruvate to acetyl CoA in mitochondrial matrix. And remaining 4Co2 are formed during Kreb's cycle. 2Co2 are released between the conversion of oxalosuccinate to alpha keto glutarate and other 2Co2 from oxidative decarboxylation of alpha keto glutarete to alpha keto glutarate.
What is the primary function of aerobic cellular respiration?
The oxygen is needed to break the sugar down.
C6H12O6 + O2 => CO2 + H2O + Energy
More specifically, in the electron transport chain, electrons are being transferred from one carrier to another. Oxygen is the final electron acceptor and is then released as water molecules. The only reason we need to breathe is so that we can have the oxygen molecules there to be the final electron acceptors.
Are cellular respiration and photosynthesis the same?
It is right because my teacher told me
and if u need the formula of respiration and photosynthesis,
here it is:
respiration
c6h12o6 + 602-> 6co2 + 6h2o + energy
Photosynthsis
6co2 + 6h2o + energy-> c6h12o6 + energy
External respiration means gas exchange between body and environment. Internal respiration means oxidation of food molecules to produce energy
What happens to each of the two molecular products in cellular respiration?
In cellular respiration, glucose is broken down into carbon dioxide and water. Carbon dioxide is a waste product that is exhaled by the organism, while water is either used by the body or excreted through urine or sweat. These products are the result of the metabolic processes that generate energy in the form of ATP for the cell.
How do cellular respiration and photosynthesis make glucose?
In photosynthesis, plants use energy from sunlight to convert carbon dioxide and water into glucose. In cellular respiration, glucose is broken down in the presence of oxygen to produce energy (ATP) that cells can use for various functions. Together, photosynthesis and cellular respiration form a continuous cycle where plants produce glucose through photosynthesis, which is then used in cellular respiration to release energy for cells.
Is cellular respiration catabolism or anabolism?
Cellular respiration is a catabolic process. It involves breaking down complex molecules such as glucose to release energy in the form of ATP.
Explain the differences and similarities of photosynthesis and cellular respiration?
Photosynthesis only happens in plants and fungi, while respiration happens with animals. In the process of photosynthesis, plants take in CO2 and water and they produce oxygen and glucose. In the process of respiration, animals take in the oxygen and glucose that the plants produce and release CO2 and water, which the plants take in. This all fit to become a cycle, which is why we and plants support one another. In the night, however, plants perform the process of respiration instead of photosynthesis. The similarities that they have is that they are both processes that provide the needs of life to the different organisms.
What do the process of photosynthesis and cellular respiration form?
The Processes Of Photosynthesis And Cellular Respiration Form Carbon Dioxide-Oxygen Cycle
How do you describe a cellular phone?
A cellular phone is a portable electronic device that allows users to make and receive calls, send text messages, and access the internet through a wireless network. It typically includes features such as a touchscreen display, camera, and various applications for communication and entertainment.
What does photosynthesis have that cellular respiration doesn't have?
Photosynthesis involves the use of sunlight to convert carbon dioxide and water into glucose and oxygen. Cellular respiration, on the other hand, breaks down glucose to produce energy in the form of ATP, releasing carbon dioxide and water as byproducts. One key difference is that photosynthesis consumes carbon dioxide and produces oxygen, while cellular respiration consumes oxygen and produces carbon dioxide.
How does photosynthesis and cellular respiration store energy to produce ATP?
Photosynthesis uses light water and carbon dioxide to produce glucose. The glucose produced is then used, with oxygen, in cellular respiration to produce ATP.
Chemical Equations
Photosynthesis
6CO2+6H2O ------> C6H12O6+6O2
Cellular Respiration
C6H12O6+6O2 ------> 6CO2+6H2O+38 ATP
NOTE *Plants use photosynthesis and cellular respiration.
*Animals just use the glucose they obtain from food to perform cellular respiration.
*This is the formula for aerobic cellular respiration not anaerobic which doesn't use oxygen and produces lactic acid in humans.
How are cellular respiration and photosynthesis almost opposite process?
Cellular respiration involves breaking down glucose to release energy with the use of oxygen, producing carbon dioxide and water as byproducts. In contrast, photosynthesis uses sunlight to convert carbon dioxide and water into glucose, releasing oxygen as a byproduct. Thus, cellular respiration consumes oxygen and produces carbon dioxide, while photosynthesis consumes carbon dioxide and produces oxygen.
What are the steps of photosynthesis and cellular respiration in order?
In photosynthesis, light energy is used to convert carbon dioxide and water into glucose and oxygen. This process occurs in the chloroplasts of plant cells. In cellular respiration, glucose is broken down in the presence of oxygen to produce carbon dioxide, water, and ATP. This process occurs in the mitochondria of both plant and animal cells.
How does this compare to the overall reaction for cellular respiration?
The overall reaction for cellular respiration is the process of converting glucose and oxygen into carbon dioxide, water, and ATP. It is the complete breakdown of glucose to release energy for the cell to use. The comparison with another reaction would depend on the specific reaction you are referring to.
Stages of aerobic cellular respiration?
There are 3 processes in aerobic respiration. Glycolysis, Kreb's cycle, and electron transport chain.
A very, very simply, the equation for all those processes is Glucose + Oxygen = Energy + Carbon Dioxide + Water.
But I will describe all these steps a little more detailed for you:
Glycolysis:
1- one molecule of glucose is converted into pyruvate
2- pyruvate is converted into acetyl CoA and CO2
3- the acetyl-CoA enters the citric acid cycle (Kreb's Cycle)
4- 2 ATP molecules, 2 water molecules, and 2 NADH molecules are produced.
Kreb's Cycle:
5- Acetyl CoA is converted into citrate which then goes through a serious of chemical transformations, losing 2 carboxyl groups as CO2 (it is converted back to acetyl CoA by losing the 2 CO2 molecules which helps the production of citric acid)
6- citric acid is broken down and makes 2 molecules of CO2
7- After 2 complete cycles of the Kreb's cycle, 6 NADH molecules, 2 FADAH2 molecules, 2 ATP molecules, and 4 CO2 molecules are produced.
The Electron Transport Chain:
8- H+ electrons from molecules produced in previous steps (H+ removed from NADH, making it NAD+)
9- the H+ are combined with O2 molecules through different membrance transports and the electrical potential between all chemicals is used to generate ATP from ADP+phosphate
10- 32-34 molecules of ATP are produced
Overall, 38 molecules of ATP are generated for every molecule of glucose in the aerobic respiration steps.
Hope this helps. Sorry if I was unclear at any point.
Does cellular respiration use oxygen?
C6H12O6 + 6O2 + 6H2O -----> 6CO2 + 12H2O + energy
Easier:
glucose (sugar) molecules + oxygen molecules = carbon dioxide molecules, water molcules, and energy
**Oxygen is used to create energy in cellular respiration**
(CO2 and H2O are waste products)

What is the function of Atp in Cellular respiration?
ATP (adenosine triphosphate) is the primary energy carrier molecule in cellular respiration. It is produced through the process of oxidative phosphorylation and is used by cells to power various cellular activities and processes, such as muscle contraction, protein synthesis, and active transport. ATP acts as a temporary energy source that can be quickly broken down to release energy for cellular functions.
Classify photosynthesis and cellular respiration according to the metabolism?
Photosynthesis is an anabolic process as it builds complex organic molecules (like glucose) using energy from sunlight, converting carbon dioxide and water into carbohydrates. Cellular respiration is a catabolic process, breaking down complex organic molecules (like glucose) to release energy in the form of ATP, which cells can use for various functions.
