The 1st Law of Thermodynamics involves

• energy conservation
• entropy (disorder)
• conservation of mass
• molecular motion

The energy stored in the H+ gradient of the mitochondrion is considered

• kinetic energy
• electrochemical potential energy
• chemical potential energy
• mechanical energy

The combination of adenine and ribose is called

• adenine dinucleotide
• adenosine
• adenosine ribonucleotide
• adenine diphosphate

The synthesis of ATP is considered an

• endergonic reaction
• exergonic reaction
• endothermic reaction
• exothermic reaction

The coupling of ATP synthesis with a highly exergonic reaction is referred to as

• the chemiosmotic generation of ATP
• substrate-level phosphorylation
• oxidative phosphorylation
• aerobic respiration

The pumping of protons across the inner membrane by proton pumps in the ETC is an example of

• active transport
• facilitated diffusion
• osmosis
• simple diffusion

Protons return to the mitochondrial matrix via ATP synthase - this is an example of

• active transport
• facilitated diffusion
• osmosis
• oxidative respiration

The mitochondrial double membrane is crucial for

• the diffusion of oxygen inwards and carbon dioxide outwards
• establishing the proton gradient
• lactic acid fermentation
• substrate-level phosphorylation

The components of the electron transport chain are arranged in order of

• increasing electronegativity
• decreasing electronegativity
• increasing molecular mass
• decreasing chemical importance
