If the proton (H+) pump in the thylakoid was not working which molecule could not be made during the light reaction?

• NADPH

• ATP

• Water

• Oxygen gas

The NADP+ is

• oxidized during the light reaction

• reduced during the light reaction

• oxidized during the Calvin cycle

• reduced during the Calvin cycle

Photosystems are made of

• chloroplasts

• chromosomes

• chlorophyll

• cytoplasm

ATP is made during the light reaction using all of the following EXCEPT

• proton pump

• hydrogen ion gradient

• electron energy from photosystem II

• NADPH donating electrons

What is FALSE about the calvin cycle

• uses the light reactions products

• produces a three carbon sugar (G3P)

• produces carbon dioxide

• produces NADP+
