Which pathway in cellular respiration will produce ATP, NADH₂, and carbon dioxide?

A) glycolysis
B) preparatory reaction
C) citric acid cycle
D) electron transport chain
E) photosynthesis

The citric acid cycle produces ATP, NADH, and carbon dioxide through a series of reactions involving the oxidation of acetyl CoA. Glycolysis also produces ATP and NADH, but does not produce carbon dioxide. The preparatory reaction converts pyruvate to acetyl CoA and produces NADH, but does not produce ATP or carbon dioxide. The electron transport chain produces ATP and uses NADH, but does not produce carbon dioxide. Photosynthesis is a process used by plants to produce glucose, and is not directly involved in cellular respiration.
