An electron transport chain is a series of protein complexes and molecules that transfer electrons and protons across a membrane, creating an electrochemical gradient that drives ATP synthesis. Learn about the mitochondrial, prokaryotic and photosynthetic electron transport chains, their components, reactions and examples.
Learn how the electron transport chain (ETC) produces ATP and regenerates electron carriers in mitochondria. The ETC involves four complexes and two mobile electron carriers that transfer electrons and protons across the inner membrane.
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.
Learn how the electron transport chain is a series of redox reactions that use oxygen to produce water and ATP in cellular respiration. The chain involves four complexes of proteins and prosthetic groups that pump hydrogen ions across the inner mitochondrial membrane.
Learn how cells use ETC to oxidize substrates and generate free energy for ATP synthesis. Explore the structure and function of ETC complexes, proton pumps, and chemiosmotic mechanism in mitochondrial respiration and photosynthesis.
Learn about the five complexes of the electron transport chain (ETC) in the mitochondria, which generate ATP by pumping hydrogen ions. Find out how uncoupling, inhibitors and free radicals affect the ETC and its clinical relevance.
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.
