Front

What are the reactants of cellular respiration?

Back

The reactants of cellular respiration are glucose and oxygen, which are obtained from the products of photosynthesis.

Front

What is the primary function of ATP in cellular respiration?

Back

ATP (adenosine triphosphate) stores energy in the bond between the second and third phosphate groups.

Front

What are the waste products of cellular respiration?

Back

The waste products of cellular respiration are water and carbon dioxide.

Front

What does glycolysis produce?

Back

Glycolysis produces 2 pyruvic acids and 2 ATP.

Front

How does a decrease in oxygen availability affect cellular respiration?

Back

A decrease in the amount of oxygen available will decrease the amount of energy produced during cellular respiration.

Front

What is the Krebs cycle?

Back

The Krebs cycle is a series of chemical reactions used by all aerobic organisms to generate energy through the oxidation of acetyl-CoA.

Front

What is the electron transport chain (ETC)?

Back

The electron transport chain (ETC) is a series of protein complexes and other molecules that transfer electrons from electron donors to electron acceptors via redox reactions.

Front

What is the role of oxygen in cellular respiration?

Back

Oxygen acts as the final electron acceptor in the electron transport chain, allowing for the production of ATP.

Front

What is fermentation?

Back

Fermentation is an anaerobic process that allows for the production of energy without oxygen, resulting in products like lactic acid or ethanol.

Front

What is the difference between aerobic and anaerobic respiration?

Back

Aerobic respiration requires oxygen and produces more energy (ATP) than anaerobic respiration, which occurs without oxygen.
