Cellular Respiration

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 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 purpose of the Krebs Cycle?

Back

The primary purpose of the Krebs Cycle is to produce electron carriers (NADH and FADH2) that are used in the Electron Transport Chain.

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 produced during glycolysis?

Back

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

Front

What is the main product of the Electron Transport Chain?

Back

The main product of the Electron Transport Chain is ATP, along with water as a byproduct.

Front

What happens to cellular respiration if oxygen is not present?

Back

If oxygen is not present, cellular respiration shifts to anaerobic processes, such as fermentation, which produces less ATP.

Front

What are the end products of cellular respiration?

Back

The end products of cellular respiration are carbon dioxide, water, and ATP.

Front

What is the significance of ATP in cellular respiration?

Back

ATP (adenosine triphosphate) is the energy currency of the cell, providing energy for various cellular processes.
