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:

• Option 1: Cellular respiration is not simply the reverse of photosynthesis' biochemical pathways.
• Option 2: Photosynthesis is not the reverse of cellular respiration's biochemical pathways.
• Option 3: Cellular respiration occurs in plants (they also do cellular respiration, not just photosynthesis) and animals. Photosynthesis occurs in plants (and some bacteria and protists), not only in plants (in a strict sense, some non - plant organisms can do photosynthesis).
• Option 4: In cellular respiration, there is a net production of ATP (not consumption), and in photosynthesis, ATP is consumed (not a net production).
• Option 5: Cellular respiration breaks down molecules (catabolic), and photosynthesis builds up molecules (anabolic).

Answer:

Cellular respiration is catabolic and photosynthesis is anabolic.
