Which of the following statements is true?

A) During cellular respiration, ATP energy is converted into carbohydrate.
B) During cellular respiration, mitochondria release oxygen.
C) During photosynthesis, energy from the sun is used to form lipids and proteins.
D) During photosynthesis, carbon dioxide is used.
E) During photosynthesis, NADH and FADH₂ are the electron carriers.

During photosynthesis, carbon dioxide is used as a source of carbon to synthesize organic molecules such as glucose. The other statements are false. ATP in cellular respiration is not converted into carbohydrate but rather carbohydrates are broken down to produce ATP. Mitochondria do not release oxygen during cellular respiration but rather use oxygen as the final electron acceptor in the electron transport chain. While energy from the sun is used during photosynthesis, it is not used to directly form lipids and proteins but rather to convert light energy into chemical energy in the form of ATP and NADPH. Lastly, NADH and FADH2 are electron carriers in cellular respiration, not photosynthesis.
