Question

two students were discussing the types of energy conversions that take place during photosynthesis and cellular respiration. here is what they said. student 1: i think that cellular respiration involves the conversion of chemical energy to chemical energy and that photosynthesis involves the conversion of radiant energy to chemical energy. student 2: i think that cellular respiration involves the transformation of chemical energy to thermal energy and that photosynthesis involves the transformation of thermal energy to chemical energy. with whom do you agree the most? explain why you agree with one student and not the other.

Explanation:

Cellular respiration converts chemical energy (from glucose) to ATP (another form of chemical energy). Photosynthesis converts radiant energy (from sunlight) to chemical energy (in glucose). Student 1 correctly states the energy conversions for both processes. Student 2 wrongly claims cellular respiration involves thermal energy conversion.

Answer:

I agree with Student 1. Student 1 accurately describes the energy conversions: cellular respiration converts chemical energy to chemical energy (ATP), and photosynthesis converts radiant energy to chemical energy. Student 2 incorrectly mentions thermal energy in cellular respiration; cellular respiration is about chemical energy transformation (glucose to ATP), not thermal energy conversion.
