2. which statement is correct about the krebs cycle?

(points : 3)
acetyl-coa combines with pyruvic acid to make glucose in the krebs cycle.
the krebs cycle produces electron carriers for the electron transport chain.
oxygen is a waste product of the krebs cycle.
in the krebs cycle, carbon dioxide is used to make glucose.

The correct option is

a. Acetyl-CoA combines with a pyruvic acid to make glucose in the Krebs cycle.

Explanation:

The Krebs citric acid cycle happens within the mitochondrial matrix and generates a pool of energy (ATP, NADH, and FADH2) from the oxidization of pyruvate, the tip product of metabolism. Pyruvate is transported into the mitochondria and loses dioxide to make acetyl-CoA, a 2-carbon molecule.
