Photosynthesis and Respiration - Medical Science

Q1:

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

A ETS (electron transfer system in light reactions

B C4 pathway

C Photosystem II

D Calvin cycle

ANS:B - C4 pathway

C4 pathway are plants that are adapted in the environment with extreme temperature, some how they have needle leaves which prevent loss of water. Their stomata are closed during the day and at night are open, where they release out carbon dioxide and take in oxygen for respiration process.
