Description

Chlorophyll a is an essential pigment in oxygenic photosynthesis. In photosystems, it is present as an antenna pigment as well as in reaction center I and II. Chlorophyll a is a blue-green pigment which absorbs light in 400 to 450 nm and 640 to 660 nm range. In photosynthesis, the energy absorbed by chlorophyll transforms carbon dioxide and water into carbohydrates and oxygen. When chlorophyll absorbs light energy, an electron in chlorophyll is excited from a lower energy state to a higher energy state. In this higher energy state, the electron is more readily transferred to another molecule. This starts a chain of electron-transfer steps, which ends with an electron transferred to carbon dioxide.
