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.
4 Σεπ 2023 · 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.
19 Ιουν 2019 · 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.
7 Οκτ 2021 · By coupling the oxidation of reducing equivalents coming into mitochondria to the generation and subsequent dissipation of a proton gradient across the inner mitochondrial membrane, this...
1 Οκτ 2020 · 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.
25 Αυγ 2023 · In electron transport, electrons are passed from mobile electron carriers through membrane complexes back to another mobile carrier. There are four inner mitochondrial membrane complexes involved in the flow of electrons to dioxygen.
1 Φεβ 2018 · In this review, we will introduce recent advances of the mitochondrial ETC (electron transport complexes) research in three parts: the structure details of respirasome, the relationship between cristae shape and respiratory chain organization, and the highly disputed issues including substrate channeling, electron transfer pathway, and the ...
