Cellular Respiration Flashcard

Front

What is cellular respiration?

Back

Cellular respiration is the process by which living organisms convert food into energy, specifically ATP, through a series of metabolic reactions.

Front

What are the main stages of cellular respiration?

Back

The main stages of cellular respiration are glycolysis, the Krebs cycle, and the electron transport chain.

Front

Where does glycolysis occur?

Back

Glycolysis occurs in the cytoplasm of the cell.

Front

What is the primary molecule broken down during cellular respiration?

Back

The primary molecule broken down during cellular respiration is glucose.

Front

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

Back

A total of 36 ATP molecules are produced from one molecule of glucose.

Front

What is the role of oxygen in cellular respiration?

Back

Oxygen is required for the Krebs cycle and the electron transport chain, making these stages aerobic.

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 final product of the Krebs cycle?

Back

The final products of the Krebs cycle include carbon dioxide, ATP, NADH, and FADH2.

Front

What is the electron transport chain?

Back

The electron transport chain is a series of protein complexes in the inner mitochondrial membrane that transfer electrons and pump protons to generate ATP.

Front

What is the difference between aerobic and anaerobic respiration?

Back

Aerobic respiration requires oxygen, while anaerobic respiration occurs without oxygen.
