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


Rate of photosynthesis       CO2 + H20 (light (enzyme reaction)) -> C6H1206 (glucose stored as starch) + O2

Increase CO2: (substrate)

Rate of P/S will increase = higher yield up to a point

Increase Temperature:

Increase temp. = increase rate of reaction = yield increase

The peak = optimum temperature

Increase temperature = no frost damage, constant temp ALL = icnrease in Yield
