What is chemiosmosis?

• The process of glycolysis

• The hypothesis that proton and electrochemical gradients are used to drive ATP synthesis

• A method of breaking down glucose into pyruvate

• The movement of oxygen in oxidative phosphorylation

What does substrate-level phosphorylation involve?

• The synthesis of ATP from ADP using an electrochemical gradient

• The synthesis of ATP from ADP using energy from breaking down a high-energy organic substrate molecule

• The oxidation of FADH2 to drive ATP production

• The process of transferring electrons in the electron transport chain

What is oxidative phosphorylation?

• The breakdown of ATP to ADP

• The synthesis of ATP from ADP using energy from electron transport

• The transfer of protons across the inner mitochondrial membrane

• The conversion of pyruvate to lactate

What generates the proton motive force (PMF)?

• A gradient of glucose molecules across the mitochondrial membrane

• A gradient of protons and a membrane potential

• The synthesis of NADH

• The movement of oxygen through the cytoplasm

What is the primary role of the proton motive force (PMF)?

• To drive the production of ATP

• To transport glucose into the mitochondria

• To break down ATP into ADP and phosphate

• To initiate the process of glycolysis
