Most CO₂ from Catabolism is Released During

Question

Most CO₂ from catabolism is released during
A)glycolysis.
B)the citric acid cycle.
C)lactate fermentation.
D)electron transport.
E)oxidative phosphorylation.

Accepted Answer

In the citric acid cycle, the acetyl-CoA produced from the breakdown of glucose is completely oxidized to CO₂, generating energy in the form of ATP and reducing power in the form of NADH and FADH₂. This CO₂ is then released as a waste product during the cycle and is the main source of CO₂ from catabolism.
