    The correct answer is b glucose is broken down into two pyruvate molecules.

    Explanation:

    Krebs cycle is one of the most important step of aerobic respiraion. Krebs cycle occur within mitochondrial matrix. During krebs cycle the acetyl CoA generated from pyruvate reacts with oxalo acetate in a cyclic manner to regenerate 4 carbon compound oxaloacetate.

    During krebs cycle pyruvate is broken down or oxidized to form 2 carbon compound known as acetyl CoA and carbon dioxide as byproduct.

    But the breakdown of glucose into two pyruvate molecules occur during glycolysis.
