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

Where does cellular respiration occur in the cell?

Back

Cellular respiration occurs primarily in the mitochondria.

Front

What is the main purpose of cellular respiration?

Back

The main purpose of cellular respiration is to produce ATP, the energy currency of the cell.

Front

What is ATP?

Back

ATP (adenosine triphosphate) is a molecule that stores and transfers energy within cells.

Front

How is energy stored in ATP?

Back

Energy in ATP is stored in the bonds between the phosphate groups, particularly between the second and third phosphate.

Front

What is the difference between aerobic and anaerobic respiration?

Back

Aerobic respiration requires oxygen and produces more ATP, while anaerobic respiration occurs without oxygen and produces less ATP.

Front

What are the main stages of cellular respiration?

Back

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

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 role do mitochondria play in cellular respiration?

Back

Mitochondria are the organelles where aerobic respiration occurs, generating ATP through the Krebs cycle and electron transport chain.

Front

What is the Krebs cycle?

Back

The Krebs cycle is a series of chemical reactions in the mitochondria that further breaks down pyruvate to produce ATP and electron carriers.
