D) GTP is generated

Question

Quizplus · Accepted Answer

The Krebs cycle does not use ATP and NADPH to reduce carbon dioxide; instead, carbon dioxide is actually released during the cycle. The Krebs cycle is also known as the citric acid cycle or the tricarboxylic acid (TCA) cycle and is a key metabolic pathway in aerobic respiration. It uses a variety of substrates, including acetyl-CoA, to generate energy in the form of ATP, GTP, and electrons for the electron transport chain.
