Unit 3b: Ch. 10 (Cell Respiration) CONCEPT CHECK

Front

What is the primary pathway for producing the maximum amount of chemical energy in cellular respiration?

Back

Aerobic respiration.

Front

What is the body's response after heavy exercise, such as running?

Back

Replenishing an oxygen loss.

Front

Which process in cellular respiration occurs regardless of the presence of oxygen?

Back

Glycolysis.

Front

True or False: Cellular respiration uses oxygen to release energy from food and produces carbon dioxide as a byproduct.

Back

True.

Front

How many ATP molecules are produced from one molecule of glucose during cellular respiration?

Back

Approximately 38 ATP.

Front

What is the role of oxygen in aerobic respiration?

Back

Oxygen acts as the final electron acceptor in the electron transport chain.

Front

What are the two main types of cellular respiration?

Back

Aerobic and anaerobic respiration.

Front

What is glycolysis?

Back

The process of breaking down glucose into pyruvate, producing a small amount of ATP.

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 (ETC)?

Back

A series of protein complexes that transfer electrons and pump protons to create a proton gradient for ATP synthesis.
