Thylakoid

(Science: plant biology) membranous cisternae of the chloroplast, found as part of the grana and also as single cisternae interconnecting the grana. Contains the photosynthetic pigments, reaction centres and [[electron Transport chain]]. Each thylakoid consists of a flattened sac of membrane enclosing a narrow intra thylakoid space.

Light-dependent Reaction Questions

... you! --- 1. My teacher says that there are three ways in which a [H+] gradient is maintained: photolysis, translocation of hydrons across the thylakoid membrane, and formation of NADPH. I am not certain why the formation of NADPH would maintain a hydron gradient, but here is my educated guess. ...
