Photosynthesis Calvin Cycle

The Calvin Cycle occurs in the

• Thylakoid

• Grana

• Inner membrane of chloroplast

• Stroma

5 carbon sugar that combines with CO2 in the Calvin Cycle

• 3-PGA

• G3P

• RuBP

• Glucose

Which of the following is true of the Calvin Cycle?

• carbon dioxide and energy (ATP and NADPH) are used to make organic compounds

• energy is absorbed from sunlight and converted to chemical energy stored in ATP and NADPH

• Occurs in the thylakoid

• Occurs in the cytoplasm

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
