36 ATP
Aerobic vs anaerobic respiration
| Aerobic | |
|---|---|
| Products | ATP, water, CO 2 |
| Location | Cytoplasm (glycolysis) and mitochondria |
| Stages | Glycolysis (anaerobic), Krebs cycle, oxidative phosphorylation |
| ATP produced | Large amount (36 ATP) |
How does aerobic respiration produce 38 ATP?
Most of the ATP produced by aerobic cellular respiration is made by oxidative phosphorylation. Biology textbooks often state that 38 ATP molecules can be made per oxidized glucose molecule during cellular respiration (2 from glycolysis, 2 from the Krebs cycle, and about 34 from the electron transport system).
How many ATP are produced in the cytoplasm during cellular respiration?
Oxygen and glucose are both reactants of cellular respiration. When one molecule of glucose is broken down, it can be converted to a net total of 36 or 38 molecules of ATP. This only occurs in the presence of oxygen.
How many ATP are produced in the Krebs cycle?
Krebs cycle also produces eight molecules of NADH2which gives 24 ATP and two molecules of FADH2which gives 2 ATP per molecule of glucose. There are 2 GTP molecule produced which are converted to form 2 ATP.
How many molecules of ATP are produced in aerobic respiration?
The table below is an “ATP account” for aerobic respiration, and shows that 32 molecules of ATP are made for each molecule of glucose used in aerobic respiration. This is the maximum possible yield; often less ATP is made, depending on the circumstances. Anaerobic respiration only produces the 2 molecules of ATP from the first two rows.
How many ATP are used in glycolysis?
Two ATP molecules are used at the start of glycolysis to phosphorylate the glucose, and these must be subtracted from the total. The table below is an “ATP account” for aerobic respiration, and shows that 32 molecules of ATP are made for each molecule of glucose used in aerobic respiration.
How is ATP made?
ATP is made in two different ways: 1 Some ATP molecules are made directly by the enzymes in glycolysis or the Krebs cycle. This is called substrate level… 2 Most of the ATP molecules are made by the ATP synthase enzyme in the respiratory chain. Since this requires oxygen it is… More
