What affects cellular respiration in plants?

Question

Vivian Aronson · Accepted Answer

Many factors affect cellular respiration in organisms:

#bb("FACTORS AFFECTING CELLULAR RESPIRATION")# 1. TEMPERATURE: Major limiting factor Optimum temperature-20-30 deg celsius 2. OXYGEN: In Aerobic #rarr#produces more energy{38ATP} In Anaerobic#rarr#produces less energy{2ATP} 3. #CO_2#{Indirectly affect respiration}: If #CO_2# concentration increases rate of respiration decreases in plants Increased concentration of #CO_2# concentration{>1%} stimulate ABA release and thus stomata become closed and hence reduces oxygen availability. 4. LIGHT: Rate of respiration increase in light intensity In twilight#rarr# morning and evening rate of photosynthesis and respiration will be 1:1 #rarr#If it occur due to light it is called light compensation point in such time there is no exchange of gases between plants and atmosphere 5. Hormones : IAA Cytokinin gibberlin ethylene{Increases Climateric Respiration} 6. Injury disease and wounds #to# enhance respiration 7. Respiratory Inhibitors: cyanides, CO, Amytal, Azide, Dinitrophenol. #rarr#hope it helps!
