Chemiosmosis
Idea that a proton gradient stores energy
What is the Chemiosmotic theory?
Final electron acceptor
What is oxygen?
Transfers electrons from NADH to Q
What is Complex 1?
Carry electrons as hydride ions
What are NAD+/ NADH?
Enzyme that makes ATP
What is ATP synthase?
Gradient that powers ATP synthesis
What is a proton gradient?
Electrons move toward higher values of this
What is reduction potential?
Does not pump protons
What is complex 2?
Contain FAD or FMN
What are flavoproteins?
Proton channel portion
Membrane that must stay impermeable
What is the inner mitochondrial membrane?
Molecule that starts the chain
What is NADH?
Transfers electrons to oxygen
What is complex 4?
Contain Fe and S
What are iron-sulfur proteins?
Proton channel portion
What is F1?
Energy from pH+ charge difference
What is proton-motive force?
Lipid-soluble mobile electron carrier
What is ubiquinone?
Contains cytochrome b and c1
What is complex 3?
Moves electrons between 3 and 4
what is cytochrome C?
Rotation-based ATP production mechanism
What is rotational catalysis?
Model linking electron flow to ATP production
What is chemiosmotic model?
Proteins with heme that carry 1 electron
What are cytochromes?
Pumps 4 protons from NADH
What is Complex 1?
Accepts 1 or 2 electrons, mobile in membrane
What is ubiquinone?
ATP made per full rotation
What is 3 ATP?
