Which of the following statements comparing photosynthesis with cellular respiration is true? A) Photosynthesis is a catabolic pathway,whereas cellular respiration is an anabolic pathway. B) Water is formed during photosynthesis but broken apart during cellular respiration. C) Both photosynthesis and cellular respiration require electron transport chains. D) Both photosynthesis and cellular respiration produce CO₂ as metabolic end products.

Question

Quizplus · Accepted Answer

Both photosynthesis and cellular respiration require electron transport chains. While photosynthesis converts light energy into chemical energy, cellular respiration breaks down organic molecules to release energy. Both reactions use electron transport chains to create a proton gradient that can be used to generate ATP. None of the other statements are true as photosynthesis is an anabolic pathway, water is broken apart during photosynthesis, and CO₂ (assuming it is meant to be CO2) is only a product of cellular respiration, not photosynthesis.
