B
Synthesis of glucose
C
Reduction of NADP+ to NADPH
D
Conversion of ADP to ATP
Verified step by step guidance1
Understand that photosynthesis consists of two main stages: the light-dependent reactions and the Calvin cycle (light-independent reactions).
Recognize that the light-dependent reactions occur in the thylakoid membranes of chloroplasts and require light energy to proceed.
Identify the key processes of the light-dependent reactions: the conversion of light energy into chemical energy, specifically in the form of ATP and NADPH.
Note that during the light-dependent reactions, water molecules are split (photolysis), releasing oxygen, and electrons are transferred to NADP+ to form NADPH.
Acknowledge that the conversion of ADP to ATP through photophosphorylation is a characteristic reaction of the light-dependent reactions, driven by the energy captured from sunlight.
