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.

What is is the order of the steps for cellular respiration?

1. Glucose is metabolised to form pyruvate (glycolysis)

Anaerobic (without oxygen):

- Pyruvate is converted to lactate or ethanol

Aerobic (in the presence of oxygen):

- Pyruvate is converted to acetyl CoA

- Citric Acid Cycle

- Electron transport chain

What phase in cellular respiration releases the oxygen?

glycosis, where a six carbon sugar is split into two molecules of a 3 carbon sugar.

How does the plant get oxygen?

Most of autotrophic plants get major amount of oxygen from photosynthesis. During night, when there is no photosynthesis, oxygen by plants is obtained from air However, the amount of oxygen released during photosynthesis by plants is manifold of their requirement for respiration.

Why is oxygen so important in cellular respiration?

Oxygen is essential in cellular respiration because it serves as the final electron acceptor in the electron transport chain, allowing for the production of the majority of ATP in aerobic respiration. Without oxygen, the electron transport chain cannot function, resulting in a significant decrease in ATP production and ultimately leading to cell death.

In which cell structure does most of the process of cellular respiration take place?

mitochondria is the organlle in which cellular respiration occurs. Tanxx for all of yaz who tak ma advice on dis i wuld noe i did a cell projec on all da organlled from cytoplasm to nucleaus and many more. Lev a questun en ill ansur it thannx.

How is energy transferred between photosynthesis and cellular respiration?

Photosynthesis:

Water + Carbon dioxide => light energy => Oxygen + Glucose

6H2O + 6CO2 + light -> 6O2 + C6H12O6

Respiration:

Oxygen + Glucose -> water + carbon dioxide + energy

6O2 + C6H12O6 -> 6H2O + 6CO2 + energy

What happens to molecules during cellular respiration?

During cellular respiration, molecules such as glucose are broken down to release energy. This process involves several stages, including glycolysis, the citric acid cycle, and oxidative phosphorylation. As glucose is metabolized, it is converted into carbon dioxide and water, with the energy released being captured in the form of ATP. Overall, cellular respiration transforms the chemical energy stored in food into usable energy for cellular activities.

What are the difference between photosythisis and cellular respiration?

First of all, photosynthesis can only occur in plants. Animals are incapable of performing this process. Cellular respiration ,however, can occur in both plants and animals. Ironically, the two processes are alike in a special way: the formula for cellular respiration is the exact reverse of the formula for photosynthesis. See the 'Related Questions' link on this page for the formulas.

Photosynthesis is an anabolic process, whereas cellular respiration is a catabolic process.

In other words, photosynthesis involves the synthesis of organic compounds while cellular respiration involves the breakdown of organic compounds.

Although photosynthesis is anabolic and cellular respiration is catabolic, both processes require an input of energy at various stages. For example, during the first stage of cellular respiration, glycolysis, an input of ATP (adenosine triphosphate) is required in order to breakup glucose into two pyruvate molecules. It is important to note that during glycolysis, 4 ATP are produced for every 2 ATP used, resulting in a net gain of 2 ATP.

How is the mitochondria of a cell like a engine?

bc the mitochrondia is also known as the power house of the cell and the power plant powers everything

Why plant cell don't perform cellular respiration?

Plants do excrete carbon dioxide as metabolic waste. Carbon dioxide is a waste product of aerobic cellular respiration, just like in humans. The carbon dioxide is excreted through the stomata on the plant's leaves.

What are the products (results) of cellular respiration?

The end products of the entire process of typical uncomplicated cellular respiration -->are 36 or 38 ATP, 6 oxygen molecules, 6 carbon dioxide molecules, and 6 water molecules.

Photosynthesis and cellular respiration are different things though, I see that your question is under the category of photosynthesis.

Photosynthesis (happens in green plants) produces glucose and oxygen.

It then uses the glucose to begin cellular respiration in it's mitochondria.. plants need ATP too.

They just use photosynthesis as a way of producing the sugar they need to produce ATP...just like we eat sugar for our energy production (cellular respiration)

What are the different cellular structures primarily responsible for photosynthesis and respiration?

for photosynthesis the structures are chloroplast,mitochondria, ribosomes, and the vacuole.And for cellular it is glucose,cytoplasm, and mitochondria.but what is Recall the substances needed for respiration

What cell organelles are responsible for photosynthesis and cellular respiration?

Photosynthesis: CO2 +H2O + Light Energy ----> O2 + carbohydrate Photsynthesis takes place in plants cells and in some bacteria. It takes place in the chloroplasts, which are little green circles of pigment. The light reactions take place in the chloroplast's thylakoids and the dark reactions take place in the stroma. The light reactions reduce water into oxygen and the dark reactions convert CO2 into energy. Respiration: O2 + carbohydrate -----> CO2 + H20 + energy CELL RESPIRATION OCCURS IN THE MITOCHONDRIA!!!!!!!

What is the main function of glucose of cellular respiration?

Glucose is the main product of photosynthesis, and it has all the stored energy from the process. The point of cellular respiration is to break down this molecule and convert its energy into ATP which is the usable energy of the cell. Essentially, the glucose provides the source of the "fuel" that runs cellular activities.

Does cell membrane perform cellular respiration?

Plasma membranes are responsible for electron transport which produces several ATP. However, in eukaryotes, the membranes is inside the mitochondria. A prokaryote must run cellular respiration on their plasma membranes that surrounds the cell.

What stage of cellular respiration yields to the most ATP?

NADH. In oxidative phosphorylation, for every NADH, around 2.5 ATP molecules are made, and for every FADH2 about 1.5 ATP molecules are made.

What is the purpose of cellular respiration reaction?

The purpose of the cellular respiration is to make carbondioxide(CO2), water(H2O) and energy which is called ATP or (Adenosine triphosphate). The main purpose is to create the ATP energy however.

What compound is released in cellular respiration?

Oxygen (O2) is released by photosynthesis during the light reaction and is used in cellular respiration. Photo. = Light energy + CO2 + Water -----> Carbohydrate + O2 Resp. = Carbohydrate + O2 -----> Energy + CO2 + Water

Which best describes respiration?

It converts Energy in food into a more usable form

Why do nerve and mucle cells contain more mitochondria than other cells?

Because nerves performe much more activity than skin cells. Where skin cells are dividing. nerves send electric impulses throught the body all the time. The impulses involve use of ATP which is produced in mitochondria.
