In the mitochondrial electron transport chain electrons move from an electron donor (NADH or QH2) to a terminal electron acceptor (O2) via a series of redox reactions. These reactions are coupled to the creation of a proton gradient across the mitochondrial inner membrane.Click to see full answer. In this manner, how are electrons transported to the electron transport chain?The electron transport chain is a series of electron transporters embedded in the inner mitochondrial membrane that shuttles electrons from NADH and FADH2 to molecular oxygen. In the process, protons are pumped from the mitochondrial matrix to the intermembrane space, and oxygen is reduced to form water.Also Know, what happens along an electron transport chain? High-energy electrons are transported from one carrier to the next. Every 2 high-energy electrons pass down the Electron Transport Chain, their energy is used to transport Hydrogen Ions across the membrane. In this manner, what are the 3 main steps in the electron transport chain? Aerobic (“oxygen-using”) respiration occurs in three stages: glycolysis, the Krebs cycle, and electron transport. In glycolysis, glucose is split into two molecules of pyruvate. This results in a net gain of two ATP molecules.How do electrons move in cellular respiration?The energy that’s released as electrons move to a lower-energy state can be captured and used to do work. In cellular respiration, electrons from glucose move gradually through the electron transport chain towards oxygen, passing to lower and lower energy states and releasing energy at each step.
