Electron gradient in biology
WebThe electron carriers deposit their electrons in the electron transport chain, a series of proteins and organic molecules in the inner mitochondrial membrane. Electrons are passed from one component to the next in a series of energy-releasing steps, allowing energy to be captured in the form of an electrochemical gradient. WebOxidative phosphorylation is made up of two closely connected components: the electron transport chain and chemiosmosis. In the electron transport chain, electrons are passed from one molecule to another, and energy released in these electron transfers is used … Step 1 Oxidative phosphorylation starts with the arrival of 3 NADH and 1 FADH 2 … Learn for free about math, art, computer programming, economics, physics, … Learn for free about math, art, computer programming, economics, physics, … And also, you just have a higher concentration, so there's a chemical …
