How Do Chloroplasts Capture Energy from the Sun?

Chloroplasts absorb sunlight and use it in conjunction with water and carbon dioxide gas to produce food for the plant. Chloroplasts capture light energy from the sun to produce the free energy stored in ATP and NADPH through a process called photosynthesis.

How do chloroplasts capture energy?

In the first step, the light reaction, chlorophyll in the grana absorbs light. The light's energy is transferred through a series of enzymes in the thylakoid membrane, resulting in the production of two energy-carrying compounds: ATP and NADPH.

How does the chloroplast capture sunlight?

Using chlorophyll in the process called photosynthesis, they convert the sun's energy into storable form in ordered sugar molecules such as glucose. ... They are compared to stacks of coins within the walls of the chloroplast, and they act to trap the energy from sunlight.
