Rate of decline of photosynthesis will be earlier than decline of respiration.

Vedclass · Answer

(B) Photosynthesis is a process that is highly sensitive to temperature because it involves enzymes like RuBisCO,which are easily denatured at higher temperatures. Respiration,on the other hand,is a catabolic process involving a series of enzymatic reactions that are generally more heat-stable than those involved in photosynthesis. Therefore,when the temperature exceeds $35^{\circ}C$,the rate of photosynthesis begins to decline due to the thermal inactivation of enzymes and the closure of stomata,while the rate of respiration continues to increase or remains stable for a longer period before it eventually declines. Thus,the rate of decline of photosynthesis occurs earlier than the decline of respiration.

If the temperature is increased (above $35^{\circ}C$),what is the effect on the rates of photosynthesis and respiration?
