Question

question 12 of 25
how are photosynthesis and cellular respiration related?
a. they are both used during fermentation.
b. one forms glucose and the other breaks it down.
c. they are both ways of forming glucose molecules.
d. both processes require an input of sunlight.

Explanation:

Photosynthesis is the process by which plants use sunlight, carbon dioxide, and water to produce glucose and oxygen. Cellular respiration is the process by which cells break down glucose and oxygen to produce energy (ATP), carbon dioxide, and water. So, photosynthesis forms glucose and cellular respiration breaks it down. Option A is incorrect because fermentation is a separate process from both. Option B is too vague. Option D is wrong as cellular respiration does not require sunlight.

Answer:

C. They are both ways of forming glucose molecules.
