Electron-flow mechanism
WebThe electrons flow through the electron transport chain, causing protons to be pumped from the matrix to the intermembrane space. Eventually, the electrons are passed to oxygen, which combines with protons to form water. The proton gradient generated by proton pumping during the electron transport chain is a stored form of energy. WebThe theory relating the formation of ATP to electron flow in the membranes of both chloroplasts and mitochondria (the organelles responsible for ATP formation during …

WebDCMU is an herbicide that acts by blocking photosynthetic electron flow from photosystem II (PSII) to the cytochrome b6f complex. Predict the effect of DCMU on O2 production and on ATP synthesis in the chloroplasts of plants sensitive to DCMU. Ans: DCMU blocks electron flow from PSII to PSI, preventing generation of O2 from H2O. WebFeb 24, 2012 · The PN junction is said to be in reverse biased condition. When there is no voltage applied across the p n junction, the potential developed across the junction is 0.3 volts at 25 o C for germanium on the junction and 0.7 volts at 25 o C for silicon p n junction. The polarity of this potential barrier is the same as the voltage source’s ...
WebRule 1: Curved arrows show movement of electron pairs, not atoms. Rule 2: Electron flow is from electron–rich (nucleophile) to electron–poor (electrophile) Rule 4: The overall charge stays the same, i.e. it’s the … WebPart B. Draw the reactants and complete the mechanism by drawing in the appropriate electron-flow arrows (including stereochemistry) for the following SN2 reaction of an alkyl bromide. Represent the nucleophile as an ion. Draw all missing reactants and/or products in the appropriate boxes by placing atoms on the grid and connecting them with ...
