Cellular Respiration

Front

What is cellular respiration?

Back

Cellular respiration is the process by which carbon-based molecules from food and oxygen are used to produce ATP, the energy currency of the cell.

Front

Where does aerobic cellular respiration occur in the cell?

Back

Aerobic cellular respiration occurs in the mitochondria.

Front

Does cellular respiration take place in all living things?

Back

Yes, cellular respiration occurs in all living things.

Front

What molecule carries energy in cells?

Back

ATP (Adenosine Triphosphate) carries energy in cells.

Front

Is cellular respiration the reverse reaction of photosynthesis?

Back

Yes, cellular respiration is the reverse reaction of photosynthesis.

Front

What are the main products of cellular respiration?

Back

The main products of cellular respiration are ATP, carbon dioxide, and water.

Front

What is the role of oxygen in cellular respiration?

Back

Oxygen is used as the final electron acceptor in the electron transport chain during aerobic respiration.

Front

What is the difference between aerobic and anaerobic respiration?

Back

Aerobic respiration requires oxygen, while anaerobic respiration occurs without oxygen.

Front

What is glycolysis?

Back

Glycolysis is the first step of cellular respiration that breaks down glucose into pyruvate, producing a small amount of ATP.

Front

What is the Krebs cycle?

Back

The Krebs cycle is a series of chemical reactions in cellular respiration that produces ATP, NADH, and FADH2 from pyruvate.
