Which of the following statements comparing photosynthesis and cellular respiration is accurate? 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. A is incorrect because photosynthesis is actually an anabolic pathway and cellular respiration is a catabolic pathway. B is incorrect because during photosynthesis, water is broken apart, releasing oxygen atoms and hydrogen ions which are used to generate energy, while during cellular respiration, oxygen gas is used to break down sugar to generate ATP. D is incorrect because while cellular respiration produces CO2 and H2O as metabolic end products, photosynthesis produces glucose and oxygen as end products.
