what is the difference between chemiosmosis and electron transport chain?
238634
In the electron transport chain, electrons are passed from one molecule to another, and energy released in these electron transfers is used to form an electrochemical gradient. In chemiosmosis, the energy stored in the gradient is used to make ATP.

The electron transport chain is the final stage of aerobic respiration leading to the forming of ATP in the inner membrane of the mitochondrion. ... The process accomplishes the pumping of four protons across the inner mitochondrial membrane to the intermembrane space.

The electron transport chain is a process that moves hydrogen ions across a membrane to produce large amounts of ATP. The final step in transferring the energy of sunlight and glucose to the usable energy of ATP takes place during the electron transport chain.

The electron transport chain is a cluster of proteins that transfer electrons through a membrane within mitochondria to form a gradient of protons that drives the creation of adenosine triphosphate (ATP). ATP is used by the cell as the energy for metabolic processes for cellular functions.

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. Electrons are passed along the chain from protein complex to protein complex until they are donated to oxygen.

Electron Transport Chain. The electron transport chain is the final component of aerobic respiration and is the only part of glucose metabolism that uses atmospheric oxygen. Electron transport is a series of redox reactions that resemble a relay race.

The electron transport chain and ATP synthase are embedded in the inner mitochondrial membrane. ... This process, in which energy from a proton gradient is used to make ATP, is called chemiosmosis. More broadly, chemiosmosis can refer to any process in which energy stored in a proton gradient is used to do work.

At the end of the electron transport chain, electrons are transferred to molecular oxygen, which splits in half and takes up H +start superscript, plus, end superscript to form water. Gradient-driven synthesis of ATP.

The electron transport chain consists of a series of enzyme complexes, which incrementally take care of the electrons that are formed when NADH and FADH2 (from the Krebs cycle) are oxidized to NAD+ and and FAD, respectively. At the same time, hydrogen ions (protons) are pumped out of the bacterial cell.

Electron transport chain. The electron transport chain is the last stage of the respiration pathway. It is the stage that produces the most ATP molecules. The electron transport chain is a collection of carrier proteins found on the inner membrane of mitochondria.

The Electron Transport System also called the Electron Transport Chain, is a chain of reactions that converts redox energy available from oxidation of NADH and FADH2, into proton-motive force which is used to synthesize ATP through conformational changes in the ATP synthase complex through a process called oxidative ...

The mitochondrial electron transport chain is a series of enzymes and coenzymes in the crista membrane, each of which is reduced by the preceding coenzyme, and in turn reduces the next, until finally the protons and electrons that have entered the chain from either NADH or reduced flavin reduce oxygen to water.

We will discuss the thermodynamics of the reactions involved in chemiosmosis and describe the limitations for ion transport and ATP synthesis that led to the proposal that at least −20 kJ/mol are required for ATP synthesis.

This flow of hydrogen ions across the membrane through ATP synthase is called chemiosmosis. Chemiosmosis (Figure 4.19 c) is used to generate 90 percent of the ATP made during aerobic glucose catabolism. The result of the reactions is the production of ATP from the energy of the electrons removed from hydrogen atoms.

The respiration reaction sequence is also known as the electron transport chain. The process of forming ATP from the electron transport chain is known as oxidative phosphorylation. Electrons carried by NADH + H+ and FADH2 are transferred to oxygen via a series of electron carriers, and ATPs are formed.

Rather, it is derived from a process that begins with moving electrons through a series of electron transporters that undergo redox reactions: the electron transport chain. ... In the process, protons are pumped from the mitochondrial matrix to the intermembrane space, and oxygen is reduced to form water.

Explanation: The electron transport chain is primarily used to send protons across the membrane into the intermembrane space. This create a proton-motive force, which will drive ATP synthase in the final step of cellular respiration to create ATP from ADP and a phosphate group.
