TRUE ANSWER : ?
YOUR ANSWER : ?

The rate of photorespiration in most plants increases at.higher temperatures. Some plants have evolved a somewhat round-about system to deal with this problem. This series of reactions is called

Calvin cycle

Photosystem II

ETS (electron transfer system in light reactions
