Electron transport chain - Wikipedia
The electron transport chain in the mitochondrion is the site of oxidative phosphorylation in eukaryotes. It mediates the reaction between NADH or succinate generated in the citric acid cycle and oxygen to power ATP synthase.
Electron Transport Chain - Definition and Steps - Biology …
2019年6月19日 · 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 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.

2023年9月4日 · The electron transport chain is a series of four protein complexes that couple redox reactions, creating an electrochemical gradient that leads to the creation of ATP in a complete system named oxidative phosphorylation. It occurs in mitochondria in both cellular respiration and photosynthesis.

Electron Transport Chain: Definition, Steps, and Diagram
2023年2月2日 · The electron transport chain (ETC) is a group of proteins and organic molecules found in the inner membrane of mitochondria. Each chain member transfers electrons in a series of oxidation-reduction (redox) reactions to form a proton gradient that drives ATP synthesis. The importance of ETC is that it is the primary source of ATP production in ...

2020年10月1日 · The mitochondrial electron transport chain utilizes a series of electron transfer reactions to generate cellular ATP through oxidative phosphorylation. A consequence of electron transfer is the generation of reactive oxygen species (ROS), which contributes to both homeostatic signaling as well as oxidative stress during pathology.

2018年6月26日 · The mitochondrial electron transport chain can produce superoxide radical (O 2 • −) from oxygen in a single electron reduction. Superoxide as a free radical can react with lipids to destroy membrane integrity, with proteins to denature them, or with mitochondrial DNA to create mutations in respiratory chain proteins (Wallace 2005 ; Orrenius ...

2024年4月8日 · The electron transport chain is located in the mitochondria. There are five main protein complexes in the ETC, located in the inner membrane of the mitochondria. These are labelled complexes I, II, III, IV, and V. The two electron carriers, NADH and FADH2, begin the chain by donating their electrons to complex I and complex II respectively.
