Final answer:
Chlorophyll of PSI is involved in reducing NADP+ to NADPH, while ATP Synthase is responsible for synthesizing ATP using the proton motive force generated during photosynthesis.
Step-by-step explanation:
The subject of this question is biology. The question refers to Chlorophyll of PSI and ATP Synthase, which are part of the photosynthetic process in plants and cyanobacteria. Chlorophyll of PSI is involved in reducing NADP+ to NADPH, while ATP Synthase is responsible for synthesizing ATP using the proton motive force generated during photosynthesis.
