Question

When there is not enough carbon dioxide in a plant, a process called photorespiration may occur. This process uses the excess oxygen in the plant, uses energy, and prevents the Calvin cycle from occurring. How would a prolonged period of photorespiration affect a plant?

Answer 1

A prolonged period of photorespiration would affect a plant, giving a significant evolutionary advantage to plant species in dry climates.

What is the difference between photorespiration and respiration?

One of the basic differences between photorespiration and respiration concerns the effect of O2 on the two processes. Respiration saturates when O2 reaches approximately 2%, while photorespiration does not reach saturation in a pure O2 atmosphere.

Under what conditions does photorespiration occur?

Photorespiration is an expensive metabolic pathway that occurs when the Calvin Cycle enzyme rubisco acts on oxygen instead of carbon dioxide.

With this information, we can conclude that A prolonged period of photorespiration would affect a plant, giving a significant evolutionary advantage to plant species in dry climates.
