It is important to create a concentration of H+  in the thylakoid space so that the H+ can diffuse through_________ to create ______.

• ATP synthase, ATP
• NADH, NADPH
• proton pump, protons

Choose the statement that best describes light reaction.

What is released as a by product of light-dependent reaction?

• oxygen

• water

• carbon dioxide

The Calvin Cycle occurs in the

• Thylakoid

• Grana

• Inner membrane of chloroplast

• Stroma

Temperatures that are too high can slow photosynthesis because

• stomata stay open to long

• enzymes can be denatured

• there is not enough CO2 in the air

• there is too much water
