What is found in a thylakoid membrane?

The thylakoid membrane, found within chloroplasts in plant cells, is primarily composed of a lipid bilayer that contains proteins, pigments, and electron transport chains. Key components include chlorophyll and other pigments that capture light energy for photosynthesis, as well as ATP synthase and various protein complexes involved in the light-dependent reactions. These structures facilitate the conversion of light energy into chemical energy, specifically in the form of ATP and NADPH.
