AP Bio Insta-Review Topic 3.6: 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, Krebs Cycle (Citric Acid Cycle), and Oxidative Phosphorylation.

Front

Where does glycolysis occur?

Back

Glycolysis occurs in the cytosol of the cell.

Front

What is the main purpose of glycolysis?

Back

The main purpose of glycolysis is to break down glucose into pyruvate, producing a small amount of ATP and NADH.

Front

Is glycolysis an aerobic or anaerobic process?

Back

Glycolysis is an anaerobic process, meaning it does not require oxygen.

Front

What is produced during the Krebs Cycle?

Back

The Krebs Cycle produces ATP, NADH, FADH2, and carbon dioxide as waste.

Front

Where does the Krebs Cycle take place?

Back

The Krebs Cycle takes place in the mitochondrial matrix.

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

Where does oxidative phosphorylation occur?

Back

Oxidative phosphorylation occurs in the inner mitochondrial membrane.

Front

What role does oxygen play in cellular respiration?

Back

Oxygen acts as the final electron acceptor in the electron transport chain, allowing for the production of ATP.
