5.2 Crop Yield

5.2 understand the effects on crop yield of increase carbon dioxide and increase temperature in glasshouses

Rate of photosynthesis:
CO2 + H2O ----light/enzyme---> C6H12O6 + 6O2

Increasing the concentration of Carbon dioxide (substrate) will increase the rate of photosynthesis producing a higher yield up until a given point.

Increasing temperature shall also increase the rate of reaction we reach the optimum temperature for the enzymes in photosynthesis. After the peak there is a sudden asymmetrical drop as the enzymes denature.
Increasing temperature also contributes to avoiding frost damage and an increased yield
