Internal Parts
Within the inner membrane, in the region called the stroma, there is a system of interconnecting flattened membrane compartments, called the thylakoids. These are the sites of light absorption and ATP synthesis, and contain many proteins, including those involved in the electron transport chain. Photosenthetics pigments such as chlorophylls a,b and c some others e.g. xanthophylls, carotenoids, phycobilins are also embedded within the granum membrane. With exception of chlorophyll a, all the other associated pigments are "accessory" and transfer energy to the reaction centers, Photosytems I and II.

Famous quotes containing the words internal and/or parts:
“I have been amazed by the Anglo-Saxon’s lack of curiosity about the internal lives and emotions of the Negroes, and for that matter, any non-Anglo-Saxon peoples within our borders, above the class of unskilled labor.”
—Zora Neale Hurston (1891–1960)
“still a betrayal room for the till-death-do-us
and yet a death, as in the unlocking of scissors
that makes the now separate parts useless,
even to cut each other up as we did yearly
under the crayoned-in sun.”
—Anne Sexton (1928–1974)
