The electron transport chain is located in the:

• Cytosol

• Mitochondrial inner membrane

• Golgi apparatus

• Nucleus

An oxidation–reduction (redox) reaction involves:

• The transfer of electrons from one molecule to another

• The addition of a phosphate group

• The movement of water across a membrane

• The breakdown of proteins into amino acids

Glycolysis is the process that: A) Requires oxygen to produce ATP B) Occurs in the cytosol and breaks down glucose into pyruvate C) Takes place in the mitochondria D) Produces a large amount of ATP

• Requires oxygen to produce ATP

• Occurs in the cytosol and breaks down glucose into pyruvate

• Takes place in the mitochondria

• Produces a large amount of ATP
