Effect of temperature on photosynthesis rate
Effect of temperature on photosynthesis rate
Rate increases to optimal point, then declines as enzymes denature
Why temperature affects photosynthesis
Why temperature affects photosynthesis
Photosynthesis is enzyme-controlled
What happens to enzymes at very high temperatures
What happens to enzymes at very high temperatures
They denature
Effect of light intensity on photosynthesis
Effect of light intensity on photosynthesis
Higher intensity = faster rate (up to a limit)
Why light intensity doesn't increase rate indefinitely
Why light intensity doesn't increase rate indefinitely
Other factors become limiting
Role of carbon dioxide in photosynthesis
Role of carbon dioxide in photosynthesis
Key reactant
Effect of CO2 concentration on photosynthesis rate
Effect of CO2 concentration on photosynthesis rate
Increases rate until other factors become limiting
Function of chlorophyll in photosynthesis
Function of chlorophyll in photosynthesis
Captures light energy
Effect of magnesium deficiency on photosynthesis
Effect of magnesium deficiency on photosynthesis
Reduces chlorophyll levels, decreasing photosynthesis rate
