What are the electron carriers in the electron transport chain?
The electron transport chain (ETC) is the major consumer of O2 in mammalian cells. The ETC passes electrons from NADH and FADH2 to protein complexes and mobile electron carriers. Coenzyme Q (CoQ) and cytochrome c (Cyt c) are mobile electron carriers in the ETC, and O2 is the final electron recipient.
How do you explain 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.
What is the role of the electron transport chain?
The electron transport chain is used to pump protons into the intermembrane space. This establishes a proton gradient, allowing protons to be pumped through ATP synthase in order to create ATP. The other two metabolic processes, glycolysis and the citric acid cycle, use substrate-level phosphorylation to generate ATP.
What is the function of the first electron transport chain?
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.
What are the components of the electron transport chain?
The electron transport chain is also called the Cytochrome oxidase system or as the Respiratory chain. The components of the chain include FMN, Fe–S centers, coenzyme Q, and a series of cytochromes (b, c1, c, and aa3)./span>
What is the main function of the electron transport chain in cellular respiration?
The primary task of the last stage of cellular respiration, the electron transport chain, is to transfer energy from the electron carriers to even more ATP molecules, the “batteries” which power work within the cell./span>
Where does the electron transport chain occur?
The electron transport chain activity takes place in the inner membrane and the space between the inner and outer membrane, called the intermembrane space.
