Question

Select all of the high energy compounds that are made during the citric acid cycle that will eventually go on to release this energy during the electron transport chain.

a. NADH
b. FADH₂
c. Glucose
d. Carbon dioxide

Answer 1

NADH and FADH₂ are the high-energy compounds made during the citric acid cycle that release energy in the electron transport chain.

Step-by-step explanation:

The high energy compounds that are made during the citric acid cycle that will eventually go on to release this energy during the electron transport chain are:

• NADH: NADH is formed when NAD+ is reduced during the citric acid cycle. It carries high-energy electrons that are used to produce ATP in the electron transport chain.
• FADH₂: FADH₂ is formed when FAD is reduced during the citric acid cycle. Like NADH, it carries high-energy electrons that are used to produce ATP in the electron transport chain.

The high energy compounds that are made during the citric acid cycle and that will eventually go on to release this energy during the electron transport chain are NADH and FADH₂. These compounds are utilized in the process known as oxidative phosphorylation, where their electrons are passed through a series of reactions, ultimately producing ATP which is the major energy currency within the cell. Glucose is not a direct product of the citric acid cycle; rather, it is broken down prior to the cycle to form Acetyl-CoA. Carbon dioxide, while produced during the cycle, is not a high-energy compound involved in producing ATP.
