Question

Why is photorespiration a wasteful reaction?

Answer 1

Answer:

Thus, photorespiration is a wasteful process because it prevents plants from using their ATP and NADPH to synthesize carbohydrates. RuBISCO, the enzyme which fixes carbon dioxide during the Calvin cycle, is also responsible for oxygen fixation during photorespiration.

Explanation:

Answer 2

Dear Student,

◆ Photorespiration is a wasteful reaction because -

• In photorespiration, RuBisCO enzyme takes up oxygen and carbon dioxide is liberated in air.
• As carbon dioxide (which is required for photosynthesis) in plants is wasted by the process of photorespiration, it is said to wasteful reaction.

Thanks dear for asking. Hope this helps you understand the concept...
