41 Electron Transport Chain Diagram

Jun 19, 2019 · The electron transport chain involves a series of redox reactions that relies on protein complexes to transfer electrons from a donor molecule to an acceptor molecule. As a result of these reactions, the proton gradient is produced, enabling mechanical work to be converted into chemical energy, allowing ATP synthesis. The electron transport chain is a series of molecules that accept or donate electrons easily. By moving step-by-step through these, electrons are moved in a specific direction across a membrane. The movement of hydrogen ions are coupled with this. This means that when electrons are moved, hydrogen ions move too.

The electron transport chain (ETC) The ETC is responsible for the reduction of molecular oxygen by NADH. This exergonic process (electrons from NADH enter at a relatively low E°′, and electrons exit at relatively high E°′ as they reduce O 2 to H 2 O. making ΔE°′ positive, and thus ΔG°′ is negative) is carried out in a precisely controlled, multistep manner that preserves much of.

Electron transport chain diagram

Protons are also special with respect to electron transport. Whenever a molecule is reduced by acquiring an electron, the electron (e-) brings with it a negative charge.In many cases, this charge is rapidly neutralized by the addition of a proton (H +) from water, so that the net effect of the reduction is to transfer an entire hydrogen atom, H + + e-(Figure 14-20B).
