U2 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 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 in the process.

Front

What are the three main stages of cellular respiration?

Back

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

Front

Where does glycolysis occur in the cell?

Back

Glycolysis occurs in the cytoplasm of the cell.

Front

What is produced during the Krebs cycle?

Back

The Krebs cycle produces ATP, NADH, FADH2, and carbon dioxide.

Front

What is the role of the electron transport chain?

Back

The electron transport chain is responsible for producing the majority of ATP during cellular respiration by transferring electrons and pumping protons.

Front

What is the final product of glycolysis?

Back

The final product of glycolysis is pyruvate.

Front

Is glycolysis an aerobic or anaerobic process?

Back

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

Front

What is the significance of NADH in cellular respiration?

Back

NADH is an electron carrier that transports electrons to the electron transport chain, where it is used to generate ATP.

Front

What happens to pyruvate in the presence of oxygen?

Back

In the presence of oxygen, pyruvate is converted into acetyl-CoA and enters the Krebs cycle.
