5.2 Crop Yield

The rate of photosynthesis
                                            light/ enzyme
Carbon dioxide + water  ----------------------->  Glucose + Oxygen
            CO2   + H20     ------------------------>C6H1206 + O2


1. Increase of concentration of carbon dioxide
If we increase the concentration of carbon dioxide ->the rate of photosynthesis will increase --> increasing in crop yield up to a point where it reaches the optimum point of the rate of photosynthesis.  That point will give you the highest yield of product. 

Increase in temperature

• If we increase the temperature then we increase the kinetic energy. 
• This causes the particles to collide into each other more frequently 
• Resulting higher chance for them to collide in correct orientation with greater temperature  ->higher rate of reaction. 

However as the rate of photosynthesis reaches the optimum ->the rate of photosynthesis starts to slow down, as some enzymes denature which decreases total crop yield.

Another effect on temperature is that it avoid frost damage and provide constant temperature
