a. Cell work → ATP→ Glucose
b. Glucose → cell work
c. ATP → Glucose
d. Glucose → ATP → cell work
2. Photosynthesis and cellular respiration are two major processes of carbon cycling in living organisms.
Which statement correctly describes one similarity between photosynthesis and cellular respiration?
a. Both occur in animal and plant cells.
b. Both include reactions that transform energy.
c. Both convert light energy into chemical energy.
d. Both synthesize organic molecules as food for the cell.

thoroughly as possible. In the diagram, molecules A
and B represent the products of photosynthesis and
molecules C and D represent the products of cellular
respiration.
