Question

Which of the following is correct?

A) Most of the ATP are produced by substrate-level phosphorylation.
B) Oxidation of FADH2 eventually yields four ATP via oxidative phosphorylation.
C) Glycolysis relies on substrate-level oxidation for the four ATP produced in this pathway.
D) Most ATP from cellular respiration are produced directly in the Krebs cycle.

Answer 1

The correct statement is that oxidation of FADH2 eventually yields four ATP via oxidative phosphorylation during cellular respiration.

Step-by-step explanation:

The correct statement out of the given options is B) Oxidation of FADH2 eventually yields four ATP via oxidative phosphorylation.

During cellular respiration, electrons from NADH and FADH2 are transferred through a series of chemical reactions to generate an electrochemical gradient via oxidative phosphorylation.

This process occurs during the electron transport system, where electrons are passed rapidly from one electron carrier to the next.

Oxidation of FADH2 leads to the production of four ATP via oxidative phosphorylation.

These ATP molecules are produced as a result of the energy harvested from the electrons during the electron transport system.
