#1
Front (Question)
Light intensity effect?
Back (Answer)
Rate increases until saturation when enzymes/CO₂ become limiting.
#2
Front (Question)
Temperature effect?
Back (Answer)
Higher temperature increases enzyme activity until denaturation.
#3
Front (Question)
CO₂ concentration effect?
Back (Answer)
More CO₂ increases fixation rate until rubisco becomes limiting.
#4
Front (Question)
Why does very high temperature reduce photosynthesis?
Back (Answer)
Rubisco and ATP synthase denature; stomata close → less CO₂.
#5
Front (Question)
Why do limiting factors matter?
Back (Answer)
Photosynthesis depends on optimum levels of all three: CO₂, temperature, and light.
