Noun
Meaning
thylakoid (plural thylakoids)
English Wikipedia has an article on:thylakoidWikipedia
(biology) a folded membrane within plant chloroplasts from which grana are made, used in photosynthesis
Examples
ATP synthase is a large protein complex that harnesses the concentration gradient of the hydrogen ions in the thylakoid space to generate ATP energy as the hydrogen ions flow back out into the stroma—much like a dam turbine.
Chlorophyll molecules are specifically arranged in and around photosystems that are embedded in the thylakoid membranes of chloroplasts.
Cryptophyte chloroplasts and some cyanobacteria don't have their phycobilin pigments organized into phycobilisomes, and keep them in their thylakoid space instead.
Embedded in the thylakoid membrane are integral and peripheral membrane protein complexes of the photosynthetic system, including the pigments that absorb light energy.
For a long time, the three-dimensional structure of the thylakoid system has been unknown or disputed.
In normal green chloroplasts, the vast majority of plastoglobuli occur singularly, attached directly to their parent thylakoid.
