Limiting factors in Photosynthesis 0.0 / 5 ? BiologyHuman, animal and plant physiologyA2/A-levelAQA Created by: meganbradfield1Created on: 09-06-16 13:45 How is the rate of photosynthesis usually measured? Vol of oxygen released by the plant; vol of CO2 taken up by the plant 1 of 5 What is the light compensation point? Amount of CO2 absorbed is balanced by the oxygen absorbed and CO2 produced by respiration (no net gas exchange) 2 of 5 What does CO2 concentration affect? Rubisco activity in the light independent reaction 3 of 5 How does temperature affect photosynthesis? A temperature above the optimum results in rates levelling off and declining due to enzyme denaturation 4 of 5 - - 5 of 5
