- Factors : Temperature -

• Chemical reactions in photosynthesis are controlled by enzymes
• The rate of photosynthesis is affected by temperature
• At low temperatures, the rate of photosynthesis is limited by the number of collisions between enzymes and substrate
• As temperature increases, the number of collisions increases, leading to an increase in the rate of photosynthesis
• At high temperatures, enzymes are denatured, which decreases the rate of photosynthesis
