ATP
C
Glucose
D
NADPH
Verified step by step guidance
1
Understand that the light reactions of photosynthesis occur in the thylakoid membranes of chloroplasts and involve the conversion of light energy into chemical energy.
Recognize that during the light reactions, water molecules are split in a process known as photolysis, which releases oxygen as a byproduct.
Identify that the light reactions also involve the generation of ATP (adenosine triphosphate) through a process called photophosphorylation, where light energy is used to add a phosphate group to ADP (adenosine diphosphate).
Acknowledge that NADP+ (nicotinamide adenine dinucleotide phosphate) is reduced to NADPH during the light reactions, which serves as a reducing agent in the Calvin cycle.
Note that glucose is not produced during the light reactions; it is synthesized during the Calvin cycle, which occurs after the light reactions and uses ATP and NADPH generated from the light reactions.
