Thylakoid

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.

Re: prokartotes

There is also the thylakoid membrane of a cyanobacterium which might qualify, but whether or not to call that an organelle would likely ignite semantic argument.

Photosynthesis question...

Splitting water releases two electrons and two protons. The electrons are used to transport the protons from the stroma to the thylakoid space. The molecules that transport protons are specific cytochromes in the electron transport chain. This proton gradient is used to synthesize ATP ...

Photosynthesis question...

Energy from the electrons is used by the molecules in the electron transport chain to transport positive H ions from the stroma into the inner thylakoid space.Is this molecule NADP?and where do they get the positive H ion from?Thanks in advance!

Photosynthesis Theory..

... The reactions for photosynthesis take place in different areas of the chloroplast. The chloroplast has three membranes (inner, outer, thylakoid) and is divided into three compartments (stroma, thylakoid space, inter-membrane space). Dark reactions occur in the stroma. Light reactions ...

Re: PROKARYOTE VS EUKARYOTE PHOTOSYNTHESIS

... required to produce carbohydrate molecules. Another system of membranes suspended in the stroma, consisting of set of flat disc like sacs called thylakoid. The thylakoid membrane encloses a fluid filled lumen or space, which is separated by thylakoid membrane with stroma. The chlorophyll is embedded ...
