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

How does the source of energy for photosynthesis nd respiration differ?

The source of energy for photosynthesis is sunlight, which is converted into chemical energy in the form of glucose. In contrast, the source of energy for cellular respiration is glucose, which is broken down to release chemical energy in the form of ATP.

What molecules do the chemical reactions occur between in cellular respiration?

In cellular respiration, the main molecules involved in the chemical reactions are glucose and oxygen. Glucose is broken down through a series of reactions to produce carbon dioxide, water, and ATP (adenosine triphosphate), which is the main energy source for cells. Oxygen is used as the final electron acceptor in the electron transport chain to drive ATP synthesis.

Is cellular respiration a function of the Golgi apparatus?

No, cellular respiration is not a function of the Golgi apparatus. The Golgi apparatus is primarily responsible for modifying, sorting, and packaging proteins for transport within or out of the cell. Cellular respiration takes place in the mitochondria and involves the breakdown of glucose to produce energy in the form of ATP.

What gases do cells use in cellular respiration?

Cells use oxygen as the main gas in cellular respiration. Oxygen is used for the process of oxidative phosphorylation to produce ATP, the cell's main source of energy. Additionally, cells also produce carbon dioxide as a byproduct of cellular respiration.

How are cellular respiration in cells and combustion alike?

They are both redox reactions involving reacting oxygen with a fuel (glucose), generating energy in the process. If you are familiar with the chemical definition of a combustion reaction, it can be seen that the overall equation of cellular respiration is exactly the same as the chemical reaction for burning glucose in air. However, even though the overall equation is the same, the actual process of cellular respiration is much more controlled than regular combustion (otherwise we'd all be burning inside our cells).

How do cells get more ATP to replace what is used in cellular respiration or photosynthesis?

Cells can generate more ATP through processes like glycolysis, the citric acid cycle, and oxidative phosphorylation in cellular respiration, or through the light-dependent and light-independent reactions in photosynthesis. These processes involve the conversion of energy stored in molecules like glucose or sunlight into ATP through a series of chemical reactions.

Which end product is of the greatest benefit to the organism in which respiration occurs?

The end product of cellular respiration that is of greatest benefit to the organism is ATP (adenosine triphosphate). ATP is the main energy carrier molecule in cells that is used for various cellular processes, providing energy for functions like muscle contraction, nerve signaling, and overall metabolic activities.

What does cellular respiration take in?

Cellular respiration requires a macromolecule to be broken down (usually glucose) and a final electron acceptor for the end of the electron transport chain (usually oxygen in most organisms). The reactants are a product of photosynthesis.

What is cellular respiration and how does it react with photosynthesis?

Cellular respiration is the process by which cells break down glucose and other organic molecules to produce energy in the form of ATP. This process involves the intake of oxygen and the release of carbon dioxide. In contrast, photosynthesis is the process by which plants, algae, and some bacteria convert light energy into chemical energy stored in glucose. Together, cellular respiration and photosynthesis are complementary processes in the carbon cycle, with the products from one process serving as the reactants for the other.

What is made for cell during cellular respiration?

Cellular respiration is the process by which food is broken down by the body's cells to produce energy in the form of ATP molecules. Cells use ATP to supply their energy needs.

In plants, some of this ATP energy is used during photosynthesis to produce sugar. These sugars are in turn broken down during cellular respiration, continuing the cycle.

In which part of cellular respiration does rotenone have its effect?

Rotenone inhibits Complex I of the electron transport chain in cellular respiration, preventing the transfer of electrons from NADH to coenzyme Q. This disrupts the flow of electrons and ultimately impairs the production of ATP.

What is the net ATP released in cellular respiration?

It produces a net gain of anywhere between 36 to 38 ATP Glycolysis produces a net gain of 2 ATP The Krebs Cycle produces a net gain of 2 ATP And the Electron Transport System (ETS) produces a net gain 34 ATP

What are the substrate for cellular respiration?

The substrates for cellular respiration are glucose and oxygen. Glucose is broken down in a series of metabolic pathways to produce energy in the form of ATP, while oxygen acts as the final electron acceptor in the electron transport chain.

Cellular respiration converts energy from which form to which 2 forms?

During cellular respiration, the energy in glucose is converted, into 40 (38 net) ATP (Adenosine triphosphate) molecules, these are then used to carry out life's functions, such as homeostasis.

What happens in the mitochondria during cellular respiration?

Yes, cellular respiration involves the mitochondria

Yes. Most of the cellular respiration takes place in mitochondria and the mitochondria membrane. That is probably why the mitochondria are known as the "Powerhouse" of the cell.

Energy used in cellular respiration can originate from?

Energy used in cellular respiration can originate from glucose, fatty acids, or amino acids, which are broken down through various metabolic pathways to produce ATP. This energy is then utilized by cells to carry out essential biological processes.

What disrupts cellular respiration?

Cellular Respiration is a three step process; Glycolysis, the Krebs Cycle, and the Electron Transport Chain. Effective cellular respiration is an aerobic cycle, meaning that it requires oxygen. The first step, glycolysis, is an anaerobic process, meaning it does not require oxygen. Therefore, glycolysis is always able to take place. The next step is the Krebs Cycle. This is an aerobic process and does not take place in the absence of oxygen. If there is an absence of oxygen, bodily toxins such as ethyl alcohol and lactic acid are produced and cellular respiration is not carried out. To answer your question, a lack of oxygen is what disrupts cellular respiration.

Does cellular respiration take in energy?

In order for cellular respiration to begin, two ATP molecules must be used up in order to breakdown the glucose molecule. Fortunately, the net gain of ATP from the first stage of cellular respiration, glycolysis, is 2 ATP. So even if oxygen is not present and fermentation has to occur, ATP is still made and not lost. However, if cellular respiration proceeds to the Krebs Cycle and carries out it's desired function, then a net gain of 36 ATP molecules will be made.

What 's the difference between two types of respiration?

Aerobic respiration requires oxygen to break down glucose into energy, while anaerobic respiration does not require oxygen and produces lactic acid or alcohol as byproducts. Aerobic respiration generates more ATP compared to anaerobic respiration.

How do the processes of photosynthesis and cellular respiration work togther?

Photosynthesis and cellular respiration are interconnected processes in living organisms. During photosynthesis, plants use sunlight to convert carbon dioxide and water into glucose and oxygen. This glucose is then used in cellular respiration by plants and animals to produce energy in the form of ATP, releasing carbon dioxide and water as byproducts which can be used in photosynthesis. This interdependence between the two processes demonstrates a continual cycle of energy and matter within ecosystems.

What releases h20 and CO cellular respiration or photosynthesis?

In cellular respiration, glucose is broken down in the presence of oxygen to release CO2 and water (H2O) as byproducts. Photosynthesis, on the other hand, utilizes CO2 and water to produce glucose and release oxygen as a byproduct.

What is the third process of cellular respiration?

The third process of cellular respiration is the electron transport chain. In this step, electrons are transferred through a series of protein complexes in the inner mitochondrial membrane, generating ATP through chemiosmosis. This is the final stage of cellular respiration where most of the ATP is produced.

The Krebs cycle and electron transport chain can produce a total of ATP?

Aerobic respiration (using oxygen) is a high energy yielding process. During the process of aerobic respiration as many as 38 molecules of ATP are produced for every molecule of glucose that is utilized. Thus aerobic respiration process breaks down a single glucose molecule to yield 38 units of the energy storing ATP molecules.

How do cellular respiration and photosynthesis starting reactants?

In cellular respiration, the starting reactants are glucose and oxygen. Glucose is broken down in the presence of oxygen to produce energy in the form of ATP. In photosynthesis, the starting reactants are carbon dioxide and water. These reactants are used in the presence of sunlight to produce glucose and oxygen.
