How many oxygen molecules are required for glycolysis?
Glycolysis requires no oxygen. It is an anaerobic type of respiration performed by all cells, including anaerobic cells that are killed by oxygen.
How many oxygen atoms are required for the complete oxidation?
It uses 5 oxygen molecules for complete oxidation of one molecule of pyruvate.
How many oxygen molecules are required each time a molecule of glucose is completely oxidized to carbon dioxide?

| Each time a molecule of glucose (C6H12O6) is completely oxidized via aerobic respiration, how many oxygen molecules (O2). are required? | 6 |
What is needed for complete oxidation of glucose?
Oxygen is necessary for complete oxidation of glucose.
How many oxygen molecules are consumed by glucose during glycolysis?
Solution: Glycolysis of one glucose molecule produces two molecules of pyruvic acid as the end product. However, during each oxidative step, no molecular oxygen is required as such. Oxidation occurs by removal of hydrogen and not addition of oxygen. So the answer is ‘Zero’.
How many oxygen molecules are consumed by glucose in glycolysis?
How many oxygen molecules are required for complete oxidation of pyruvic acid?
1 glucose produces 2 pyruvic acid molecules and therefore, 3O2 or 6 atoms of oxygen are required for 1 molecule of pyruvic acid.
How many oxygen molecules are required?
Molecular oxygen (O2) is a diatomic molecule that is composed of two oxygen atoms held together by a covalent bond. Molecular oxygen is essential for life, as it is used for respiration by many organisms….Properties.
| Chemical formula | O2 |

How many oxygen molecules O2 are required to each time a molecule of glucose C6H12O6 is completely oxidized to carbon dioxide and water via answer choices?
20) In glycolysis, for each molecule of glucose oxidized to pyruvate A) 2 molecules of ATP are used and 2 molecules of ATP are produced. B) 2 molecules of ATP are used and 4 molecules of ATP are produced. C) 4 molecules of ATP are used and 2 molecules of ATP are produced.
Is oxygen is necessary for complete oxidation of glucose?
Answer: Absence of oxygen during glucose breakdown produces pyruvic acid and alcohol. Presence of oxygen during aerobic breakdown of glucose produces water and carbon dioxide along with the release of a large amount of energy. Hence, oxygen is necessary for the complete oxidation of glucose.
Why is oxygen required for glucose oxidation?
NADH and FADH2 carry electrons to specialized cell membranes, where they are harvested to create ATP. Once the electrons are used, they become depleted and must be removed from the body. Oxygen is essential for this task. Used electrons bind with oxygen; these molecules eventually bind with hydrogen to form water.
