Compare and contrast the processes of photosynthesis and aerobic respiration. How are they similar
and how do they differ? What will be an ideal response?
Concepts to Consider: Overall, aerobic respiration can be considered the opposite of photosynthesis.
The reactants of respiration are the products of photosynthesis. In addition, respiration is an exergonic
process, whereas photosynthesis is endergonic and uses the energy of the sun. In addition, both
processes occur in different areas of the cell. Photosynthesis and aerobic respiration have similar
electron transport chains, where electrons are transferred from one acceptor to another as a means of
generating a proton gradient used in the chemiosmotic synthesis of ATP.
