5.2 Crop yield

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

Photosynthesis equation

CO2 + H2O => C6H12O6 (glucose) + 6O2


Things that will increase the rate of reaction, the rate of photosynthesis and consequently the crop yield

1. Carbon dioxide concentration

• Increasing the concentration of a substrate will result in the rate of reaction 
• increasing and then remaining constant after a certain point
• In this case, carbon dioxide
• The rate / crop yield will increase until a certain point (the optimum)

2. Temperature

• Higher temperature - higher rate of reaction until the optimum temperature is surpassed and the enzymes denature
• (Particles can collide into each other more frequently due to increased kinetic energy, but a temperature surpassing the optimum would cause the substrate to no longer be able to bind to the active site)
• Avoiding frost damage, maintaining constant temperature
