Question

where is the light energy converted into an electron flow?
a) within the nadp+ molecule
b) in the reaction center chlorophyll
c) at each individual accessory pigment molecule
d) at the atp - synthase

Explanation:

In photosynthesis, light - energy is absorbed by chlorophyll in the reaction center. When light is absorbed, an electron in the reaction - center chlorophyll gets excited and is transferred, starting an electron flow. NADP+ is involved in the electron - transport chain but not the initial conversion site. Accessory pigments transfer energy to the reaction center but don't directly convert light to electron flow. ATP - synthase is involved in ATP production, not the initial light - to - electron conversion.

Answer:

B. In the reaction center chlorophyll
