Homework Answers
Answer: During cellular respiration, glycolysis produces two NADH molecules and tricarboxylic acid cycle (TCA) produces 6 NADH molecules per glucose molecule. These NADH molecules are electron carriers and provide electrons to components of the electron transport chain, leading to synthesis of ATP molecules. Hence, option b is the correct answer and other options are incorrect.

In glycolysis, one glucose molecule yields pyruvates, ATP and NADH. Depending on the system used to shuttle the electrons from NADH into mitochondria, these NADH become NADH or FADH2. Converting the pyruvate(s) into acetyl-CoA's produces 2 NADH. One pyruvate/Two pyruvates pass(es) through the citric acid cycle starting with acetyl-CoA produces GTP, FADH2, and NADH. In the electron transport chain, each FADH2 generates ATP and each NADH ATP.
