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.

depends on what you mean by "group." for order, it would be coleoptera (beetles). for class, it would be insecta (insects). for phylum, it would be the arthropoda (animals with jointed exoskeletons).
