electron transport chain in thylakoid membrane

Explanation: Water supply the initial electron in photosynthesis. The electron transport chain moves protons across the thylakoid membrane into the lumen. NADH release the hydrogen ions and electrons into the transport chain. The second electron will then shoot up and travel down a similar electron transport chain… In the process of cellular respiration, the molecules of NADH donates some of the electrons, which passes through the electron transport chain. Biochim Biophys Acta. The net result is a low pH in the thylakoid lumen, and a high pH in the stroma. The electron transport chain is a series of protein complexes and electron carrier molecules within the inner membrane of mitochondria that generate ATP for energy. 1976 Feb 16; 423 (2):313–322. The thylakoid membrane is where much of this occurs, and we will discuss its role here. Effects of magnesium and chloride ions on light-induced electron transport in membrane fragments from a blue-green alga. At the same time, splitting of water adds protons to the lumen, and reduction of NADPH removes protons from the stroma. Schematic of electron transport and proton translocation in the thylakoid membrane. The electron transport chain is a collection of proteins found on the inner membrane of mitochondria. In cellular respiration, a molecule of _____ supplies the electron that travels through the electron transport chain. Biochim Biophys Acta. Which of the following best explains the mechanism by which photosystem I (PS I) and photosystem II (PS II) operate during linear electron flow? ; Electrons are passed along the chain from protein complex to protein complex until they are donated to … Ono T, Murata N. Photosynthetic electron transport and phosphorylation reactions in thylakoid membranes from the blue-green alga Anacystis nidulans. 1)Electrons flow from PS I to PS II, gaining potential energy to be later used in … At the same time, splitting of water adds protons to the lumen, and reduction of NADPH removes protons from the stroma. Here is the rest of the question: In the thylakoid membrane, two photosystems are involved in the light reactions of photosynthesis. reation of a pH gradient by pumping protons across the thylakoid membrane Carbon fixation in the stroma Removal of electrons from chlorophyll molecules Reduction of NADP+ molecules ... oxidation of electron transport chain between the two photosystems light absorbtion reduction of primary electron acceptor. In the process, protons are pumped from the mitochondrial matrix to the intermembrane space, and oxygen is reduced to form water. In photosynthesis, the electron that travels through the electron transport chain in the thylakoid membrane comes from _____. The electron transport chain moves protons across the thylakoid membrane into the lumen. In photosynthesis, the electrons that travel through the electron transport chain in the thylakoid membrane comes from water. The electron transport chain is a series of electron transporters embedded in the inner mitochondrial membrane that shuttles electrons from NADH and FADH 2 to molecular oxygen. energizes an electron in the green organic pigment chlorophyll, enabling electron to move along an electron-transport chain in the thylakoid membrane. In eukaryotic organisms, the electron transport chain is found embedded in the inner membrane of the mitochondria, in bacteria it is found in the cell membrane, and in case of plant cells, it is present in the thylakoid membrane of the chloroplasts. The net result is a low pH in the thylakoid lumen, and a high pH in the stroma. The chlorophyll obtains its electrons from water by producing oxygen as a by products.
