Which description accurately compares cellular respiration and photosynthesis?
a) photosynthesis uses energy captured from sunlight to power the reduction of carbon dioxide to sugars; cellular respiration oxidizes sugars to yield energy for the cell.
b) the atp produced via cellular respiration is needed to power the reactions of photosynthesis
c) the pathways of photosynthesis are those of cellular respiration run in reverse.
d) photosynthesis captures energy from sunlight to oxidize carbon dioxide to sugars; cellular respiration reduces these sugars to yield energy for the cell.

The correct answer will be option-A.

Explanation:

Photosynthesis is a process which uses sunlight energy to synthesize food in the form of glucose. The process takes place in the chloroplast in two stages: light-dependent reactions and light-independent reactions.

The light-independent reaction produces to convert the carbon dioxide from the atmosphere to glucose through the Calvin cycle. The carbon gets fixed and reduced form+4 state to +1 state.

Respiration is the process which oxidizes the glucose molecule to produce energy in the form of ATP molecules. This ATP is utilized by the cell to perform various functions.

Thus, option-A is the correct answer.
