Compounds like succinate,fumarate and α-ketoglutarate have a catalytic effect on the consumption of oxygen in a cell suspension.The rate of oxygen consumption is far more than that required for their own oxidation.This is evidence that ________.

Question

Quizplus · Accepted Answer

The fact that succinate, fumarate, and α-ketoglutarate are causing a higher rate of oxygen consumption than needed for their own oxidation suggests that they are involved in a cyclic pathway. This type of cyclic pathway is known as the citric acid cycle (also called the Krebs cycle or TCA cycle), which involves a series of redox reactions that ultimately result in the generation of ATP.
