Thylakoid in Biological Definition

Chloroplast

... actually takes place. A stack of thylakoids is called a granum . A thylakoid looks like a flattened disk, and inside is an empty area called the thylakoid space or lumen. The photosynthesis reaction takes place on the surface of ...

ATP synthase

... place). Plant ATP synthase In plants ATP synthase is also present in chloroplasts (CF O F 1 -ATP synthase). The enzyme is integrated into thylakoid membrane; the CF 1 -part sticks into stroma , were dark reactions of photosynthesis ( Calvin cycle ) and ATP synthesis take place. The overall ...

Chloroplast membrane

... inner membrane, in the region called the stroma , there is a system of interconecting flattened membrane compartments, called the lamellae , or thylakoid membrane . These are sites of light absorption and ATP synthesis, and contain many proteins, including those involved in the electron transport ...

Proton-motive force

... from the citric acid cycle and is utilized in the synthesis of ATP via ATP Synthase . In plants, the Proton Motive Force also exists in the thylakoid membranes of the chloroplast , where it is generated by the light reaction of photosynthesis and used to synthesize ATP for use in the ...

Stroma

... 1) The connective supportive framework of a biological cell , tissue , or organ . 2) The fluid filled area of a chloroplast outside of the thylakoid membranes wherein the light-independent reactions ( Calvin Cycle and Carbon fixation ) of photosynthesis take place. ...

Thylakoid

... A thylakoid is part of an internal membrane system of chloroplasts folded repeatedly into a stack of disks called grana . It contains chlorophyll , which ...
