Verified step by step guidance

Understand the context of the Krebs Cycle, also known as the Citric Acid Cycle, which is a key metabolic pathway that occurs in the mitochondria and is crucial for energy production.

Identify the main reactants involved in the Krebs Cycle. The cycle begins with Acetyl-CoA, which combines with oxaloacetate to form citrate. NAD+ and FAD are also important reactants as they are involved in the redox reactions within the cycle.

Recognize the main products of the Krebs Cycle. As the cycle progresses, carbon dioxide (CO2) is released as a waste product. NADH and FADH2 are produced as they carry electrons to the electron transport chain, and ATP is generated as a direct energy source.

Evaluate the options given in the problem. Compare each set of reactants and products to the known reactants and products of the Krebs Cycle.

Select the option that correctly lists Acetyl-CoA, NAD+, and FAD as reactants, and CO2, NADH, FADH2, and ATP as products, which aligns with the biochemical processes of the Krebs Cycle.
