Chemiosmosis and electron transport chain
WebIn the electron transport chain, oxygen serves as the last electron acceptor, taking electrons and protons to create water (H2O). Through a process known as chemiosmosis, ATP synthase is driven to produce ATP as a result of this activity, which creates a proton gradient across the mitochondrial membrane. Protons flow down the gradient, WebThe electron transport chain passes electrons to oxygen in a series of steps instead of one explosive reaction. It breaks the large free-energy drop from food to O2 into …

WebJan 20, 2024 · Electron transport is a series of chemical reactions that resembles a bucket brigade in that electrons from NADH and FADH 2 are passed rapidly from one ETS electron carrier to the next. These carriers can pass electrons along in the ETS because of their redox potential. WebMay 25, 2024 · The energized electrons are then used to make NADPH. The electron transport chain is a series of molecules that accept or donate electrons easily. By moving step-by-step through these, electrons are moved in a specific direction across a membrane. The movement of hydrogen ions are coupled with this.

WebMar 14, 2024 · The electron transport chain is a crucial step in oxidative phosphorylation in which electrons are transferred from electron carriers, into the proteins of the electron transport chain which then deposit the … WebChemical reactions in the electron transport chain generate free energy that is used to pump hydrogen ions across the membrane during chemiosmosis, establishing an electrochemical gradient. The inner mitochondrial membrane only allows ions of hydrogen to pass through it thanks to a membrane protein called ATP synthase.
