What is the correct difference in energy transformation between photosynthesis and cellular respiration?
Answer and explanation
Correct answer: Photosynthesis stores light energy as chemical energy, whereas cellular respiration releases energy from glucose.
Photosynthesis is an endothermic process in which light energy is used to store chemical energy in glucose formed from carbon dioxide and water. In contrast, cellular respiration oxidises glucose and releases energy, which is used to form ATP. Option B is incorrect because photosynthesis does not release energy from glucose; it stores energy in glucose.
