During photosynthesis, the following reaction takes place:

carbon dioxide + water + light energy → sugar + oxygen

During cellular respiration, the following reaction takes place:

sugar + oxygen → carbon dioxide + water + chemical energy

Given this information, how are photosynthesis and cellular respiration related?
A.
The same type of energy is found in both photosynthesis and cellular respiration.
B.
The products of photosynthesis are the reactants of cellular respiration.
C.
Photosynthesis and cellular respiration both produce the same materials.
D.
Photosynthesis and cellular respiration both start with the same materials.

1 answer

The correct answer is:

B. The products of photosynthesis are the reactants of cellular respiration.

This is because the sugar and oxygen produced during photosynthesis are used as reactants in cellular respiration, which then produces carbon dioxide and water, the reactants needed for photosynthesis.
