Explanation:
Detailed explanation-1: -Answer and Explanation: Oxaloacetate is an intermediate of the Krebs cycle but not an end product of the cycle.

Detailed explanation-3: -Note that this process completely oxidizes 1 molecule of pyruvate, a 3 carbon organic acid, to 3 molecules of CO2. During this process, 4 molecules of NADH, 1 molecule of FADH2, and 1 molecule of GTP (or ATP) are produced.
Detailed explanation-4: -The end products of pyruvate processing is Acetyl Coenzyme A and NADH. Pyruvate is oxidatively decarboxylated to leave an acetyl group.
