AP - Unit 3: Cellular Respiration

Front

What is ATP and its role in cellular respiration?

Back

ATP (Adenosine Triphosphate) is the primary energy carrier in cells, produced during cellular respiration and used for various cellular processes.

Front

Where does aerobic respiration occur in the cell?

Back

Aerobic respiration occurs in the mitochondria of the cell.

Front

What is glycolysis and what does it produce?

Back

Glycolysis is the metabolic pathway that converts glucose into two molecules of pyruvic acid, producing a small amount of ATP.

Front

What are the byproducts of cellular respiration?

Back

The byproducts of cellular respiration include carbon dioxide (CO2), water (H2O), and heat.

Front

What is the difference between aerobic respiration and glycolysis in terms of ATP production?

Back

Aerobic respiration produces nearly 20 times more ATP than glycolysis alone.

Front

Define 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 significance of the mitochondria in cellular respiration?

Back

Mitochondria are known as the powerhouse of the cell, where aerobic respiration takes place, producing ATP.

Front

What is the role of oxygen in aerobic respiration?

Back

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

Front

What is fermentation and how does it differ from aerobic respiration?

Back

Fermentation is an anaerobic process that produces energy without oxygen, resulting in byproducts like lactic acid or ethanol, unlike aerobic respiration which requires oxygen.

Front

What is the citric acid cycle and where does it occur?

Back

The citric acid cycle (Krebs cycle) occurs in the mitochondria and is a key part of aerobic respiration, producing electron carriers for the electron transport chain.
