In aerobic respiration, how many pryuvic acids are produced from one glucose molecule?

Answer 1

Since glucose has 6 carbons/molecule and pyruvic acid has 3, and since no other carbon atoms are added or taken off during glycolysis, you should be able to conclude how many pyruvic acids are formed from one glucose.

Answer 2

Generally 2
but when 2-hydroxyacetone is very little or absent then the pathway turn a bit.
And only one pyruvic acid is formed from 2-phoshoglyceraldehyde.

So maximum 2 minimum 1.

By the way.
Glycolysis is regarded as anaerobic process.
So take care.
