During the process of photosynthesis, plants use energy from the sun to convert carbon dioxide and water into glucose and oxygen. these products are, in turn, used by the plant or animals that eat the plant during cellular respiration to produce atp.

atp molecules store cellular energy. when phosphate groups are removed and molecules of adp are formed, energy is released. this energy can be used to
perform

a. electron transport.
b. cellular work.
c. diffusion.
d. osmosis.
