How many ATP are produced from one molecule of glucose?

Question

What is the net gain and what is the total number of ATP produced?

Answer 1

By aerobic respiration,  36 net ATP are produced, but 38 total.

Answer 2

It depends how the glucose is metabolized, by aerobic respiration or by fermentation.

Answer 3

actually either 36 or 38 total ATPs are produced by a combination of glycolysis ( net 2 ), the glycerol-phosphate shuttle ( 4 ) or the malate/aspartate shuttle (6 ) plus  30 ATPs

from the 2GTPs in TCA, the 2 FADH2s, the 8 NADHs ( 2 from PDH ) and 6 from TCA ). Remember this is the total for two pyruvates entering per mole of glucose ( 2 3C fragments from 1 6 C compound ). Depending on which shuttle is used for the extramitochondrial NADH reducing equivalent generated in glycolysis...the total yield may be 36 or 38 ATPs from glucose .

Answer 4

In aerobic respiration, one molecule of glucose yields 38 ATP molecules, eight produced during glycolysis, six from the link reaction and 24 from the Krebs cycle.

The net gain is 36 ATP, as two of the ATP molecules produced from glycolysis are used up in the re-oxidation of the hydrogen carrier molecule NAD.

Answer 5

Aerobic Respiration: total of 38

Fermentation: 2
