The energy released during the chain of electron transport molecules is used to create a(n) ____ gradient across the inner mitochondrial membrane for chemiosmosis.

A) ADP
B) ATP
C) proton
D) oxygen
E) electron

Chemiosmosis

Chemiosmosis is the movement of ions across a selectively permeable membrane, down their electrochemical gradient, fundamental in processes like ATP synthesis in cells.

Proton Gradient

A gradient formed by the difference in proton concentrations across a membrane, often used to generate ATP in cellular respiration and photosynthesis.

Mitochondrial Membrane

The membrane that encloses the mitochondrion, consisting of an outer membrane and an inner membrane with folds known as cristae, where energy production occurs.
