CH 10 Cellular Respiration Vocabulary Flashcard

Front

What is the first step in cellular respiration?

Back

Glycolysis: The process where a molecule of glucose is broken down into two molecules of pyruvic acid.

Front

What process allows ATP production without oxygen?

Back

Fermentation: A metabolic process that keeps glycolysis going in the absence of oxygen.

Front

What organelle is the site of aerobic respiration in eukaryotic cells?

Back

Mitochondria: Organelles that generate ATP through aerobic respiration.

Front

What is a calorie?

Back

A unit of energy defined as the amount of energy needed to raise the temperature of 1 gram of water by 1 degree Celsius.

Front

What type of respiration does not require oxygen?

Back

Anaerobic respiration: A form of respiration that occurs without oxygen.

Front

What is the Krebs cycle?

Back

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?

Back

A sequence of protein complexes and other molecules that transfer electrons from electron donors to electron acceptors via redox reactions.

Front

What is ATP?

Back

Adenosine triphosphate: The primary energy carrier in all living organisms.

Front

What is the role of oxygen in aerobic respiration?

Back

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

Front

What is the difference between aerobic and anaerobic respiration?

Back

Aerobic respiration requires oxygen and produces more ATP, while anaerobic respiration occurs without oxygen and produces less ATP.
