I. Oxidative Phosphorylation Flashcards

0
Q

From here?

A

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.

NADH and FADH

A

Deliver the electrons and H+ to the transmembrane proteins. Most of them are called cytochromes

Q

The final terminal electron acceptor is?

A

Oxygen

As oxygen receives the electrons and combine with 2 H+ a molecule of water is formed

Q

The free energy released from electron transport chain (ETC) is used to power?

A

Proton pumps embedded in the Cristae to pump protons out of the matrix into the inter membrane space

Q

This creates?

A

An electrochemical gradient called proton motive force. Source of potential energy to power the chemiosmosis that will follow

Q

Chemiosmosis

A

The protons flow back through the Cristae to relieve the proton motive force gradient through a channel enzyme/protein called ATP syntase
