I. Oxidative Phosphorylation Flashcards
From here?
the electrons move from one carrier to another in the chain. Occurs from a carrier with less electronegativity to a carrier that has more EN.
Spontaneous downhill reaction
NADH and FADH
Deliver the electrons and H+ to the transmembrane proteins. Most of them are called cytochromes
The final terminal electron acceptor is?
Oxygen
As oxygen receives the electrons and combine with 2 H+ a molecule of water is formed
The free energy released from electron transport chain (ETC) is used to power?
Proton pumps embedded in the Cristae to pump protons out of the matrix into the inter membrane space
This creates?
An electrochemical gradient called proton motive force. Source of potential energy to power the chemiosmosis that will follow
Chemiosmosis
The protons flow back through the Cristae to relieve the proton motive force gradient through a channel enzyme/protein called ATP syntase
ATP syntase
Harnesses the proton-motive force energy to phosphorylate ADP to form ATP
