Question

which of the following statements about the relationship between photosynthesis and cellular respiration is correct?
in cellular respiration, the biochemical pathways of photosynthesis run in reverse.
in photosynthesis, the biochemical pathways of cellular respiration run in reverse.
cellular respiration occurs only in animals, and photosynthesis occurs only in plants.
there is a net consumption of atp in cellular respiration and a net production of atp in photosynthesis.
cellular respiration is catabolic and photosynthesis is anabolic.

Explanation:

• Cellular respiration breaks down glucose (catabolic) to release energy, while photosynthesis builds glucose (anabolic) using energy from sunlight.
• The first two options are incorrect because the biochemical pathways of photosynthesis and cellular respiration are not simply reverses of each other.
• Cellular respiration occurs in both plants and animals (so the third option is wrong).
• In cellular respiration, there is a net production of ATP, and in photosynthesis, ATP is consumed during the Calvin cycle (so the fourth option is incorrect).

Answer:

Cellular respiration is catabolic and photosynthesis is anabolic.
