How is chlorophyll arranged?
1 Answer
Most of the chlorophyll molecules are physically involved with intrinsic proteins, forming chlorophyll-protein complexes.
Explanation:
Chlorophyll molecules and structural proteins are assembled in the following complexes:
The Photosystem (PS) I complex which has the reaction center molecule P700 (pigment absorbing at 700 nm).and a high chlorophyll a /chlorophyll b ratio.
The PS II complex which has a low a/b ratio and is present mainly in grana thylakoids.
Chlorophyll is an asymmetrical molecule having a hydrophilic head made of four pyrrole rings bound to each other and forming a porphyrin. In chlorophyll, there is a Mg atom forming a complex with the four rings.. Chlorophyll has a long hydrophobic chain, attached to one of the rings.
