The function(s) of chloroplast’s membrane system is/are

(a) trapping of light energy

(b) synthesis of ATP

(c) synthesis of NADPH

Select the correct option.

The functions of the chloroplast's membrane system are:

• Trapping of light energy: The chloroplast's thylakoid membrane contains pigments like chlorophyll that are responsible for capturing light energy from the sun. This trapped light energy is utilized in the process of photosynthesis to convert water and carbon dioxide into glucose and oxygen.
• Synthesis of ATP: During the light-dependent reactions of photosynthesis that take place in the thylakoid membrane, light energy is used to generate ATP (adenosine triphosphate) molecules. ATP is a high-energy molecule that acts as the primary energy currency of the cell, providing energy for various cellular processes.
• Synthesis of NADPH: The light-dependent reactions in the thylakoid membrane also produce NADPH (nicotinamide adenine dinucleotide phosphate), which is a molecule that serves as an electron carrier. NADPH plays a crucial role in the light-independent reactions (Calvin cycle) of photosynthesis, where it supplies the necessary electrons for the reduction of carbon dioxide to form glucose.
