AP Biology 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 three main stages of cellular respiration?

Back

The three main stages are Glycolysis, the Citric Acid Cycle (Krebs Cycle), and Oxidative Phosphorylation.

Front

Where does glycolysis occur in the cell?

Back

Glycolysis occurs in the cytoplasm of the cell.

Front

What is the end product of glycolysis?

Back

The end product of glycolysis is pyruvate.

Front

What is the role of Acetyl CoA in cellular respiration?

Back

Acetyl CoA is a key molecule that enters the Citric Acid Cycle after being produced from pyruvate.

Front

What is produced during the Citric Acid Cycle?

Back

The Citric Acid Cycle produces ATP, NADH, FADH2, and carbon dioxide.

Front

What is oxidative phosphorylation?

Back

Oxidative phosphorylation is the final stage of cellular respiration where ATP is produced using the electron transport chain and chemiosmosis.

Front

What is the function of ATP?

Back

ATP (adenosine triphosphate) serves as the primary energy carrier in cells.

Front

What is fermentation?

Back

Fermentation is an anaerobic process that allows for the production of energy without oxygen, resulting in products like lactic acid or ethanol.

Front

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

Back

Up to 38 ATP molecules can be produced from one glucose molecule during cellular respiration.
