24. What is/are the major potential energy product (s) formed in the Krebs Cycle (not the same as end-products formed a the end of cellular respiration) ?

a. NADH/FADH2

c. Carbon dioxide

b. Adenosine Tri-phosphate

d. Glucose

Answer: a. NADH/FADH2

Explanation:

Complete oxidative degradation of glucose can be compartmentalized into four main biochemical steps: glycolysis, the formation of acetyl-CoA, the Krebs (citric acid or tricarboxylic acid cycle) and the electron transport chain where oxidative phosphorylation is performed. During respiration, an organic compound (usually sugar) is completely oxidized to form CO2 and H20. The Krebs cycle is the set of reactions leading to complete oxidation of glucose. It occurs in the mitochondria of eukaryotes and the cytoplasm of prokaryotes. Per each degraded glucose molecule, resulting in the final of the Krebs cycle:

• 6 molecules of NADH.

• 2 molecules of FADH2

• 2 molecules of ATP

• 4 molecules of CO2

Which gives our answer What is/are the major potential energy product (s) formed in the Krebs Cycle? a. NADH/FADH2 because 8 molecules of them in total are made.
