Describe the two main phases of photosynthesis, including where they occur and the role of NADP+.

Here are the answers to your questions:

1.2.1

• Phase A: Light-dependent phase
• Phase B: Light-independent phase (or Calvin cycle)

1.2.2

• Phase A: Thylakoid membranes
• Phase B: Stroma

1.2.3
NADP (Nicotinamide adenine dinucleotide phosphate) acts as an electron carrier. It accepts electrons and hydrogen ions during the light-dependent phase (Phase A) to form NADPH, which then carries these to the light-independent phase (Phase B) to reduce carbon dioxide and synthesize glucose.
