Question

what captures light in order to begin the process of photosynthesis? adenosine triphosphate chlorophyll nicotinamide mesophyll

Explanation:

Chlorophyll is a pigment in plants that absorbs light energy, which is the initial step for photosynthesis. Adenosine triphosphate (ATP) is an energy - carrying molecule produced during photosynthesis, not the light - capturing agent. Nicotinamide is related to coenzymes and not involved in light capture for photosynthesis. Mesophyll is the tissue in plant leaves where photosynthesis occurs, not the light - capturing substance.

chlorophyll
