The thylakoid lumen is a continuous aqueous phase enclosed by the thylakoid membrane.

Thylakoid lumen

The major aims of this work were to design a procedure for the isolation of the thylakoid lumen which could be generally used to characterize lumenal proteins. Thylakoid lumen is the innermost aqueous compartment of the chloroplast. It is enclosed by a thylakoid membrane. It plays an important role in the ATP synthesis or phosphorylation driven by chemiosmosis. Protons are pumped across the membrane into the lumen, which generates concentration gradient across the thylakoid membrane. The inside of the thylakoid membrane is called the lumen, and outside the thylakoid membrane is the stroma, where the light-independent reactions take place.

[See accompanying illustration at right.] The electron transport chain moves protons across the thylakoid membrane into the lumen. At the same time, splitting of water adds protons to the lumen, and reduction of NADPH removes protons from the stroma.

LIGHT HARVESTING COMPLEXES IN HIGHER PLANTS

The thylakoid lumen which is enclosed by the thylakoid membrane is a continuous aqueous phase. It is important especially for photophosphorylation in photosynthesis. The protons are pumped into the lumen via the membrane while reducing the pH level. The electron transport chain moves protons across the thylakoid membrane into the lumen.

Reason. play. 30698774. The light reactions of photosynthesis occur in the thylakoid membranes.

The net result is a low pH in the thylakoid lumen, and a high pH in the stroma. ATP synthase uses this electrochemical gradient to make ATP. Understanding the roles of the thylakoid lumen in photosynthesis regulation It has been known for a long time that the thylakoid lumen provides the environment for oxygen evolution, plastocyanin-mediated electron transfer, and photoprotection. the thylakoid membrane encloses a narrow, continuous com-partment, the lumen (1, 2). Electron microscopy studies of spinach thylakoids have suggested that the lumen is a densely packed space (3).

Because Mar 9, 2007 In the absence of any information on the function of thylakoid lumen proteases, Deg1 protease in particular, we sought to determine its (2007). The thylakoid lumen protease Deg1 is involved in the repair of photosystem II from photoinhibition in Arabidopsis.

It functions as a cofactor for violaxanthin–de-epoxidase (VDE), the enzyme involved in the formation of nonphotochemical quenching. Thus, it is necessary for photoprotection (Toth et al., 2013). 2. Thylakoid struktur . I kloroplaster är tylakoider inbäddade i stroma (en inre del av en kloroplast).

The protons are pumped into the lumen via the membrane while reducing the pH level. The electron transport chain moves protons across the thylakoid membrane into the lumen.
