Question

An important product of the citric acid cycle is production of NADH

and FADH2. These molecules generate ATP by...
a. Releasing their nicotinamide and flavin subunits to become
ATP
b. Converting GTP into ATP
c. Extracting high-energy electrons from CO2.
d. Transporting high-energy electrons that power
oxidative phosphorylation.
e. Using high-energy electrons to power Na+-K+ ATPase.

Answer 1

The citric acid cycle produces NADH and FADH2, which transport high-energy electrons that power oxidative phosphorylation to generate ATP.

Step-by-step explanation:

The citric acid cycle, also known as the Krebs cycle, is a series of redox and decarboxylation reactions that remove high-energy electrons and carbon dioxide. These high-energy electrons are stored in molecules of NADH and FADH2. These molecules then transport the high-energy electrons to the electron transport chain in the mitochondria, where ATP is generated through oxidative phosphorylation. Therefore, option d is the correct answer - transporting high-energy electrons that power oxidative phosphorylation.
