The Krebs Cycle Extracts Most of the Energy in a Glucose

Question

The Krebs cycle extracts most of the energy in a glucose molecule and stores it in:
A) pyruvic acid.
B) ATP.
C) CO2.
D) NADH.
E) O2.

Accepted Answer

The Krebs cycle produces NADH, which contains high-energy electrons that will be used later in the electron transport chain to create ATP. The other options (pyruvic acid, ATP, CO₂, and O₂) are not products of the Krebs cycle or do not play a major role in storing energy from glucose.
