The sequence of membrane proteins of the electron transport chain includes three transport proteins and other electron transport proteins. As the electrons from original glucose molecules move through the proteins, work is done. The electron transport chain produces a(n) _____ concentration gradient.
Figure 1. 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. In the process, protons are pumped from the mitochondrial matrix to the intermembrane space, and oxygen is reduced to form water.
An electron transport chain (ETC) is a series of complexes that transfer electrons from electron donors to electron acceptors via redox (both reduction and oxidation occurring simultaneously) reactions, and couples this electron transfer with the transfer of protons (H + ions) across a membrane.
By moving during the protein they give it power like water moving through a dam. when hydrogen ions move through the protein and down the electron transport chain ,ATP is created . this is how plants turn sunlight into chemical energy that they can use.
The electron transport chain is where most energy cells are generated. This "chain" is actually a series of protein complexes and electron carrier molecules within the inner membrane of cell mitochondria , also known as the cell's powerhouse.
Oxidative phosphorylation works by using energy-releasing chemical reactions to drive energy-requiring reactions: The two sets of reactions are said to be coupled.This means one cannot occur without the other. The flow of electrons through the electron transport chain, from electron donors such as NADH to electron acceptors such as oxygen, is an exergonic process – it releases energy ...
Transfer of electrons between carriers in the electron transport chain in the membrane of the cristae is coupled to proton pumping AND In chemiosmosis protons diffuse through ATP synthase to generate ATP AND Oxygen is needed to bind with the free protons to maintain the hydrogen gradient, resulting in the formation of water

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).
