Question

what do photosynthesis and cellular respiration both have? electron transport chains, but with different proteins identical mechanisms for generating energy from organic compounds electron transport chains with the same proteins identical molecules undergoing the same chemical reactions during both processes

Explanation:

Photosynthesis and cellular respiration both have electron - transport chains. However, the proteins involved in these chains are different between the two processes. Photosynthesis occurs in plants and some microorganisms to convert light energy into chemical energy, while cellular respiration in cells breaks down organic compounds to release energy. The mechanisms for generating energy from organic compounds are different between them, and the molecules and chemical reactions are also not identical.

Answer:

electron transport chains, but with different proteins
