Maximizing Photosynthesis

Question 1

What happens if the light intensity is increased?

Answer 1

The rate of photosynthesis is eventually limited by another factor.

Question 2

What would get produced at the high proportion of energy concentracted at those wavelengths?

Answer 2

It would produce a high rate of photosynthesis.

Question 3

What does Carbon Dioxide Concentrations in a Graph refer to?

Answer 3

• An increase in the carbon dioxide concentration increases the rate at which carbon is incorporated into carbohydrate in the light-independent reaction so the rate of photosynthesis generally increases until limited by another factor.

Question 4

How does Temperature play a role?

Answer 4

• Photosynthesis is dependent on ambient air and leaf temperatures.
• It is a reaction catalyzed by enzymes.
• As the enzymes approach their optimum temperatures the overall rate increases.
• Above the optimum temperature the rate begins to decrease until it stops.
