Complex I transfers electrons (initially derived from food) from the coenzyme NADH (nicotinamide adenine dinucleotide) to the ...

The reactions of the electron transport chain are carried out by a series of membrane proteins and organic molecules. They are arranged in four complexes.

Complex I transfers electrons (initially derived from food) from the coenzyme NADH (nicotinamide adenine dinucleotide) to the other complexes in the chain. Part of the complex also functions as an ...

When scientists typically analyze how supercomplexes form, they use antibodies to measure one or two proteins per electron transport chain complex. But as there can be up to 44 proteins in a complex, ...

Mitochondrial respiratory chain Definition: The protein complexes that form the mitochondrial electron transport system (the respiratory chain), associated with the inner mitochondrial membrane.The ...

The team set out to obtain 3D structures of three components in the electron transport chain -- complex III, complex IV and supercomplex III-IV.

As electrons (e –) flow along the electron-transport chain, protons (H +) are pumped from the matrix to the intermembrane space through complexes I, III, and IV and then back into the matrix ...

This discovery also links a point mutation in complex I to Leber hereditary optic neuropathy, affecting proton-sodium exchange without disrupting electron transport. This summary was automatically ...
