• Explain how CO2 enters leaves. What environmental factors control stomatal movement? How are these factors related to physical and chemical properties that control the opening and closing of stomata?
• What are primary stages in the photosynthetic carbon reduction (PCR) cycle? Explain the role of each stage. Draw a diagram of the stages by utilizing drawing tools in Microsoft^® Word to aid your explanation.
• Explain how the ATP and NADPH produced by the photosynthetic electron transport chain are used in the PCR cycle.

• Explain how cells release energy through glycolysis, respiration, and fermentation. Identify pathways in each stage. Describe each stage’s role in releasing energy.
• What is the role of enzymes in degrading starch and sugar? Explain your answer.
• Discuss some similarities and differences between respiration and fermentation.
