Thylakoid membrane
What molecules from the light-dependent reactions provide the energy to fix carbon into high-energy molecules in the Calvin Cycle?
ATP
NADPH
ADP
NADP+
What enzyme combines the carbon from atmospheric carbon dioxide with the intermediate molecule RuBP (Ribulose Biphosphate) in the Calvin Cycle?
RuBisCo
Catalase
ATP Synthase
NADP+ Reductase
How many G3P molecules are required to create one glucose molecule?
1

The chlorophyll pigments absorb light (photons) in photosystems II and I. This energy splits water into oxygen, hydrogen ions, and electrons. As these electrons are passed along the transport chain, what actions result from the energy they transfer?
Hydrogen is pumped into the thylakoid from the stroma, building up a concentration gradient
ATP is regenerated by ATP synthase
NADPH is regenerated by NADP+ reductase
Glucose is broken down to provide energy
