Question

Why is photorespiration considered a wasteful process?

Answer 1

Explanation:

bcz instead of ATP gain thereis loss of ATP in this process that's why its a wasteful process.

Answer 2

Photorespiration is a wasteful process as it prevents plants from using their ATP to prepare carbohydrates.

• Photorespiration occurs when the concentration of oxygen is more and there is presence of light. An enzyme called rubisco utilizes oxygen as a substrate rather than carbon-di-oxide.

• Photorespiration is a process that uses oxygen, releases carbon-di-oxide without producing sugar. In a way this process restricts the more useful process of Photosynthesis.

• This light-activated respiration occurs in the chloroplasts of some plants.

• The process not only interferes with photosynthesis but in addition, does not give any useful by products like ATP which are energy rich molecules. Its end product is carbon-di-oxide.
