8. what is a reaction center? a an electron carrier that transports electrons to the dark reaction b a carbohydrate molecule that is produced during photosynthesis o c a high-energy molecule that acts as the energy currency for the cell d a pigment molecule that transfers electrons during the light reaction whitch letter is it a, b, c, or d

a pigment molecule that transfers electrons during the light reaction-D

The correct answer is option D pigment molecule that transfers electrons during the light reaction

Explanation:

A photosynthetic reaction center is a complex molecule formed of proteins, chlorophyll pigment and other co-factors present in the photo-system.

These reaction centers are present in the photosystems which are found in the thylakoid membranes of plants, algae and cytoplasm of cyanobacteria.

Reaction center converts the light energy absorbed by the pigment molecule called chlorophyll in plants which energize the electrons and bring them in motion thus, start a chain of electrons passing energy to higher electrons.

Thus, option D pigment molecule that transfers electrons during the light reaction is the correct answer.
