The primary purpose of the Krebs cycle is to
A)complete the oxidation of foodstuffs using NAD and FAD as hydrogen (electron)carriers.
B)catalyze the phosphorylation of ADP from creatine phosphate.
C)oxidize foodstuffs and transfer those electrons to pyruvic acid.
D)convert lactate to pyruvate.

Question

Quizplus · Accepted Answer

The Krebs cycle, also known as the citric acid cycle, is a series of enzymatic reactions that complete the oxidation of foodstuffs such as glucose, fatty acids, and amino acids, producing ATP, NADH, and FADH2 as energy-rich compounds. NAD and FAD serve as hydrogen (electron) carriers in the cycle, enabling the transfer of electrons to the electron transport chain for the production of additional ATP. Therefore, choice A is the correct answer. Choices B, C, and D are incorrect as they do not accurately describe the primary purpose of the Krebs cycle.
