BIOL-L112 Chapter 9 Terms

Complete Transfer

Results in the complete transfer of an electron from one molecule to another.

Incomplete Transfer

Results in a change in the degree of electron sharing in covalent bonds.

Respiration

Oxidation of glucose and other molecules into food.

Glycolysis (1st stage of Cellular Respiration)

Occurs in the cytosol, oxidation of glucose into 2 pyruvate molecules.

Pyruvate Oxidation and the Citric Acid Cycle (2nd stage of Cellular Respiration)

Occurs in the mitochondria matrix, oxidation of pyruvate to Acetate CoA.

Oxidative Phosphorylation (3rd stage of Cellular Respiration)

Occurs on the inner membrane of the mitochondria in eukaryotes.

Citric Acid Cycle

Takes place in mitochondria matrix, also called Krebs Cycle and TCA Cycle.

Matrix of Mitochondria

Where the Citric Cycle occurs

Inner Membrane of Mitochondria

Where oxidative phosphorylation occurs

Interspace Membrane

Where the proton motive force exists.

Chemiosmosis

Energy stores in the H+ gradient (Proton Motive Force) drives the synthesis of ATP.
