Problem
I. If testing for photosynthesis rates using air, what method could you use to assess if photosynthesis is occurring?
II. If testing for photosynthesis rates using glucose, how could you measure the amount of glucose in a subject?
III. In the electron transport chain, a series of proton pumps build an electrochemical gradient across the inner mitochondrial membrane.
i. If pores were added to this membrane, allowing the diffusion of protons across the membrane, what would happen to the proton gradient?
ii. Would ATP still be made as efficiently as when there were no pores? Why or why not?
IV. Understanding photosynthetic processes can increase food yield. In Ontario, a number of fresh vegetables are grown all year in greenhouses. This allows the grower to control the conditions of the plants.
i. Identify three abiotic factors that can be controlled and the impact of each on photosynthesis.
ii. How can a grower affect each factor?
