The phase of catabolism during which ATP production is highest is:
A) digestion.
B) glycolysis.
C) oxidation.
D) citric acid cycle.

Question

Quizplus · Accepted Answer

The citric acid cycle (also known as the Krebs cycle) is the phase of catabolism during which ATP production is highest. This is because it is the point at which the majority of the energy stored in nutrients is released and used to produce ATP. Glycolysis also plays a role in ATP production, but the overall ATP yield is lower compared to the citric acid cycle. Digestion and oxidation do not directly produce ATP.
