Question

NADH and FADH2 carry high-energy electrons that are used to pwoer the production of ATP in the mitochondria. These cofactors are generated during glycolysis, the citric acid cycle, and the fatty acid oxidatoin cycle. Which molecule below can produce the most ATP?

a)NADH from glycolysis
b)FADH2 from fatty acid cycle
c)NADH from krebs
d)FADH2 from krebs

Answer 1

FADH2 from the Krebs cycle can produce the most ATP.

Step-by-step explanation:

The molecule that can produce the most ATP is FADH2 from the Krebs cycle. During the Krebs cycle, FADH2 is generated and enters the electron transport chain, where it donates electrons to pump protons and produce ATP through chemiosmosis.

The electrons from FADH2 produce slightly fewer ATP compared to NADH, but still contribute to the overall production of ATP.
