The products of glucose oxidation that are essential for oxidative phosphorylation are:

Acetyl CoA

NADH and FADH₂

NADPH and ATP

Pyruvate

Why is glycolysis described as having an investment phase and a payoff phase?

It both splits molecules and assembles molecules

It uses glucose and generates pyruvate

It uses stored ATP and then forms a net increase in ATP

It attaches and detaches phosphate groups

Almost all of the oxygen (O₂) a person consumes in breathing is converted to ______ during oxidative phosphorylation:

CO₂

Acetyl CoA

H₂O

C₆H₁₂O₆

Where does oxidative phosphorylation take place?

Cytosol

Ribosomes

Thylakoid membrane

Mitochondria

Chemiosmosis is an integral part of oxidative phosphorylation, and is defined as:

The active transport of ions across a cell membrane against their concentration gradient

The movement of ions across a selectively permeable membrane down their concentration gradient

Transfer of a phosphate group from a substrate to ADP to form ATP

The movement of electrons down an electron transport chain

When hydrogen ions are pumped from the mitochondrial matrix across the inner membrane and into the intermembrane space, the result is the:

Formation of ATP

Reduction of NAD⁺

Creation of a proton gradient

Oxidation of oxygen
