Question

What is the significance of photorespiration?

Answer 1

Answer:

Significance of photorespiration is that it proportionates the amount of carbon dioxide in the plant.

Answer 2

Answer:

Photorespiration is a biochemical system in plants where oxygen inhibits the Calvin cycle, the carbon fixation portion of photosynthesis, particularly under conditions of water pressure.

Explanation:

This is a type of metabolism where plants intake oxygen and give out carbon dioxide i.e when carbon dioxide is less in concentration and oxygen is high, rubisco uses oxygen as a substrate instead carbon dioxide. So here ATP and sugar is not produced. This process takes place in dry hot days where the plant is forced to close its stoma to prevent loss of water.
