5.75 Oxidative phosphorylation and the chemiosmotic theory

Electrons pass along the chain and some of their energy is used to pump protons across the membrane

What does the electron transport chain do?

Flow of protons , down their concentration gradient, across a membrane, through a channel associated with ATP synthase

What is chemiosmosis?

The formation of ATP using energy released in the electron transport chain in the presence of oxygen

What is oxidative phosphorylation?

Reduced NAD and FAD are deoxidised when they deliver H atoms to the electron transport chain

What is the first step of chemiosmosis?

32

What is the net gain of ATP in respiration?

The H atom released from reduced coenzymes split into protons and electrons

What is the second step of chemiosmosis?

The protons go into solution in the mitochondrial matrix

What is the third step of chemiosmosis?
