Cellular Respiration Review

Front

What is cellular respiration?

Back

Cellular respiration is the process by which cells convert glucose and oxygen into energy (ATP), carbon dioxide, and water.

Front

What is the main purpose of cellular respiration?

Back

The main purpose of cellular respiration is to produce ATP, which is the energy currency of the cell.

Front

What is ATP?

Back

ATP (adenosine triphosphate) is a molecule that stores and transfers energy within cells.

Front

What is the ATP/ADP cycle?

Back

The ATP/ADP cycle is the process of converting ADP back into ATP by adding a phosphate group, thus storing energy.

Front

Which organisms perform cellular respiration?

Back

Both animals and plants perform cellular respiration.

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 produced during glycolysis?

Back

Glycolysis produces 2 ATP molecules, 2 NADH molecules, and 2 pyruvate molecules.

Front

What is the Krebs cycle?

Back

The Krebs cycle, also known as the citric acid cycle, is a series of chemical reactions used by all aerobic organisms to generate energy.

Front

Where does the Krebs cycle take place?

Back

The Krebs cycle takes place in the mitochondria of the cell.
