Verified step by step guidance

Understand the role of the citric acid cycle in cellular respiration. It is a key metabolic pathway that connects carbohydrate, fat, and protein metabolism.

Recognize that the citric acid cycle, also known as the Krebs cycle, takes place in the mitochondria of the cell.

Identify the main products of the citric acid cycle: NADH, FADH2, and a small amount of ATP (or GTP). These products are crucial for the electron transport chain.

Clarify that the citric acid cycle itself does not directly use oxygen. Instead, oxygen is the final electron acceptor in the electron transport chain, which is linked to the citric acid cycle.

Evaluate the statements given: The false statement is that the citric acid cycle directly uses oxygen as a reactant, as oxygen is not directly involved in the cycle itself.
