In green plants, the primary function of the Calvin cycle is to

• Use ATP to release carbon

• Split water to release oxygen.

• Construct sugar from carbon dioxide.

• Use NADPH to release carbon

• ATP

• sugar

• NADPH

Connecting ideas: There are enzymes that help with chemical reactions during photosynthesis. Temperatures that are too high can slow photosynthesis because

• stomata stay open

• enzymes are ruined

• there is not enough CO2

• there is too much water

• carbohydrate
• source of quick energy
• all are correct

What are the inputs of the Calvin Cycle (Light-Independent Reactions)?

• NADPH

• ATP

• CO₂

• H₂O

• chlorophyll

Connecting Ideas: Which of these conditions would decrease the rate of photosynthesis in a plant?

• Above average precipitation
• Changing the daylight hours from 14 hrs to 10 hrs
• Changing the CO₂ concentration from 380 ppm to 410 ppm
• All of these choices
