The graph shows the citric acid cycle. During the citric acid cycle what happens to acetyl-CoA?

A) it enters the citric acid cycle engage carbon dioxide to form citric acid engage more carbon dioxide do redox reactions to form a four carbon molecule
B) it enters the citric acid cycle and associates with a four carbon molecule form is citric acid and then through redox reactions jet regenerates the four carbon molecule air
C) it enters glycolysis and associates with a five carbon molecule the redox reactions forming another acetyl-CoA
D)It enters the citric acid cycle and associates with a four carbon molecule forming a five carbon compound and then through oxidation reactions regenerates the four-carbon molecule

It enters the citric acid cycle and associates with a 4-carbon molecule, forming citric acid, and then through redox reactions regenerates the 4-carbon molecule.

Answer:

B) it enters the citric acid cycle and associates with a four carbon molecule form is citric acid and then through redox reactions jet regenerates the four carbon molecule.

Explanation:

Acetyl CoA enters the citric acid cycle and reacts with a four carbon compound, that is, oxaloacetate. The reaction forms citric acid (6 carbons) which in turn undergo redox reactions to regenerate the oxaloacetate and the released electrons are accepted by NAD+ and FAD+. The final products of citric acid cycle are CO2, H2O, NADH and FADH2.
