Krebs cycle (or Citric acid cycle)
This breaks down the pyruvic acid to carbon dioxide. This produces 2 ATP and 6 NADH , for every glucose molecule entering glycolysis. The Krebs cycle takes place inside the mitochondria. The Krebs cycle produces the CO2 that you breath out.
Furthermore, in what stage of cellular respiration is carbon dioxide produced?
Since there are two pyruvic acid molecules entering the system, two ATP molecules are formed. Also during the Krebs cycle, the two carbon atoms of acetyl-CoA are released and each forms a carbon dioxide molecule.
Secondly, how is carbon dioxide produced in aerobic respiration? During aerobic cellular respiration, glucose reacts with oxygen, forming ATP that can be used by the cell. Carbon dioxide and water are created as byproducts. In cellular respiration, glucose and oxygen react to form ATP. Water and carbon dioxide are released as byproducts.
In this manner, is co2 produced in aerobic respiration?
Cells undergoing aerobic respiration produce 6 molecules of carbon dioxide, 6 molecules of water, and up to 30 molecules of ATP (adenosine triphosphate), which is directly used to produce energy, from each molecule of glucose in the presence of surplus oxygen.
What stage of aerobic respiration produces the most ATP?
Here is the breakdown of net ATP production:
- Glycolysis: 2 ATP.
- Krebs Cycle: 2 ATP.
- Oxidative Phosphorylation (Electron Transport Chain/Chemiosmosis): 28 ATP.
- Fermentation: 2 ATP.

Which part of cellular respiration produces the most co2?
The Krebs cycle produces the CO2 that you breath out. This stage produces most of the energy ( 34 ATP molecules, compared to only 2 ATP for glycolysis and 2 ATP for Krebs cycle).
What part of respiration produces carbon dioxide?
The Krebs Cycle A small amount of ATP is also made during this process. This process occurs in a continuous cycle, named after its discover, Hans Krebs. The Krebs cycle uses a 2-carbon molecule (acetyl-CoA) derived from pyruvate and produces carbon dioxide.
What is the process of respiration?
Respiration is the biochemical process in which the cells of an organism obtain energy by combining oxygen and glucose, resulting in the release of carbon dioxide, water, and ATP (the currency of energy in cells).
Where is oxygen used in aerobic respiration?
What is ATP cycle?
The process of phosphorylating ADP to form ATP and removing a phosphate from ATP to form ADP in order to store and release energy respectively is known as the ATP cycle. Adenosine triphosphate is an energy source that is used in living things. ATP is created during cellular respiration.
What is the process of aerobic respiration?
Aerobic respiration is the process of producing cellular energy involving oxygen. Cells break down food in the mitochondria in a long, multistep process that produces roughly 36 ATP. Aerobic respiration is the process of breaking down the food that comes into a cell using oxygen to help power that process.
What is ATP used for?
The Adenosine triphosphate (ATP) molecule is the nucleotide known in biochemistry as the “molecular currency” of intracellular energy transfer; that is, ATP is able to store and transport chemical energy within cells. ATP also plays an important role in the synthesis of nucleic acids.
How many ATP are made in aerobic respiration?
Where is co2 produced in aerobic respiration?
Aerobic Respiration. This process occurs in the cytoplasm. Each pyruvate molecules is oxidized to carbon dioxide and a 2-carbon acetyl group. Each of the 2-carbon acetyl groups produced from the original glucose molecule is bonded to a pre-existing molecule of oxaloacetate to form citrate (i.e. citric acid).
What is the end product of aerobic respiration?
The end products of aerobic respiration are 38 atp of energy, carbon dioxide and water while of anaerobic respiration is ethanol and 2atp of energy. Aerobic respiration occurs when your cells produce energy in the presence of oxygen.
Is more co2 produced in aerobic or anaerobic respiration?
Advantages of Aerobic Respiration This releases only enough energy to make two ATP molecules. With oxygen, organisms can break down glucose all the way to carbon dioxide. This releases enough energy to produce up to 38 ATP molecules. Thus, aerobic respiration releases much more energy than anaerobic respiration.
What is the byproduct of respiration?
Carbon dioxide and water are the by-products of cellular respiration – they are substances that are created in cellular respiration but are not needed. When you look at the reactants for cellular respiration, you can see there are various carbon, oxygen, and hydrogen atoms.
What is the difference between breathing and respiration?
What is the difference between breathing and respiration? Breathing is the physical process where you inhale and exhale air in and out of your lungs. Respiration is a chemical reaction where Oxygen is used to breakdown Glucose in order to generate energy which is then used by the cell to function.
Where does aerobic respiration occur?
The cells take in glucose and produce ethanol (alcohol) and carbon dioxide. Most aerobic respiration happens in the mitochondria, but anaerobic respiration takes place in the fluid portion of the cytoplasm.
