Which of the following is true of the Calvin Cycle?

Increasing carbon dioxide can increase photosynthesis, but only to a maximum rate because

• There are not enough RuBP molecules

• Oxygen cannot leave fast enough

• Large amounts of CO2 cannot fit in the chloroplast

• Calvin cycle can only go as fast as the light reactions

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

In the Calvin Cycle, ________ and ________ from the light dependent reactions convert PGA into G3P

• O_2, ATP
• CO₂, H₂
• ADP, NADPH
• NADPH, ATP

The 5-Carbon molecules that the Calvin Cycle starts and ends with, is called _____________.

• PGA
• G3P
• RuBP
• RuDp

• ATP, Glucose
• Glucose, RUBP
