Question

Which of the following statements about energy metabolism is FALSE?

a) Cellular respiration is the reciprocal process to photosynthesis.
b) Animals rely on consuming other organisms for their energy.
c) Plants provide the H₂O and CO₂ that animals need to carry out respiration.
d) The main objective of respiration is to break down glucose to release energy.

Answer 1

Plants do not specifically provide the water and carbon dioxide needed for animal respiration.

Step-by-step explanation:

The statement that is FALSE about energy metabolism is:
c) Plants provide the H₂O and CO₂ that animals need to carry out respiration.

In reality, animals get oxygen mainly from the air they breathe, while plants produce oxygen as a byproduct of photosynthesis. During cellular respiration, oxygen is used to break down glucose and release energy, while carbon dioxide is produced as a waste product. So, plants do not specifically provide the water and carbon dioxide needed for animal respiration.
