Question

1. which pigment absorbs light energy during photosynthesis?

a. nadp⁺
b. chlorophyll
c. atp
d. carotene

Explanation:

To solve this, we analyze each option:

• Option a: $\text{NADP}^+$ is a coenzyme involved in electron transport, not a pigment that absorbs light.
• Option b: Chlorophyll is the primary pigment in plants that absorbs light energy (specifically in the visible spectrum) for photosynthesis. It's the main pigment responsible for capturing light in the photosystems.
• Option c: ATP is an energy - carrying molecule, produced during photosynthesis, not a pigment that absorbs light.
• Option d: Carotene is an accessory pigment that absorbs light, but chlorophyll is the main pigment that absorbs light energy for photosynthesis.

Answer:

b. Chlorophyll
