Question

during the citric acid cycle, what happens to acetyl-coa? it enters the citric acid cycle and gains carbon dioxide to form citric acid, and gains more carbon dioxide through redox reactions to form a 4 - 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. it enters glycolysis and associates with a 5 - carbon molecule through redox reactions, forming another acetyl - coa molecule. it enters the citric acid cycle and associates with a 4 - carbon molecule, forming a 5 - carbon compound, and then through oxidation reactions regenerates the 4 - carbon molecule.

Explanation:

In the citric acid cycle, acetyl - CoA combines with a 4 - carbon molecule (oxaloacetate) to form citric acid (a 6 - carbon compound). Through a series of redox reactions, carbon dioxide is released, and the 4 - carbon molecule (oxaloacetate) is regenerated.

Answer:

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.
