Continue your comparison of electron transport and chemiosmosis in mitochondria and chloroplasts. In each case,a. where do the electrons come from?b. how do the electrons get their high potential energy?c. what picks up the electrons at the end of the chain?d. how is the energy released as electrons are transferred down the electron transport chain used?

Chemiosmotic creation of ATP is driven by:

a) Phosphate transfer through the plasma membrane.

b) Potential energy of the H⁺ concentration gradient created by the electron transport chain.

c) Substrate-level phosphorylation in the mitochondrial matrix.

d) Large quantities of ADP in the mitochondrial matrix.

The electron transport chain pumps H⁺ ions into which location of the mitochondria?

a) Mitochondrial intermembrane space. 

b) Mitochondrial matrix.

c)  Mitochondrial inner membrane.

d) The H⁺ ions are pumped out of the mitochondria.
