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 the electron transport chain in cellular respiration?

Back

The electron transport chain uses high-energy electrons to convert ADP into ATP, the energy currency of the cell.

Front

Where does glycolysis occur in the cell?

Back

Glycolysis occurs in the cytoplasm of the cell.

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 through the oxidation of acetyl-CoA.

Front

What happens to the Krebs cycle in the absence of oxygen?

Back

The Krebs cycle does not occur if oxygen is not present.

Front

Which organisms perform cellular respiration?

Back

Both autotrophs and heterotrophs perform cellular respiration.

Front

What is the equation for aerobic cellular respiration?

Back

C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O.

Front

What is ATP?

Back

ATP (adenosine triphosphate) is the primary energy carrier in all living organisms.

Front

What are the two main types of cellular respiration?

Back

The two main types of cellular respiration are aerobic respiration (requires oxygen) and anaerobic respiration (does not require oxygen).

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.
