What is metabolism?

Back

Metabolism is the set of life-sustaining chemical reactions in organisms that convert food into energy.

Front

What are the two main types of metabolism?

Back

The two main types of metabolism are catabolism (breaking down molecules to release energy) and anabolism (building up molecules for growth and repair).

Why do cells need glucose?

Back

Cells need glucose because it is a primary source of energy that is used in cellular respiration to produce ATP.

Front

What role do amino acids play in metabolism?

Back

Amino acids are the building blocks of proteins, which are essential for growth, repair, and various metabolic processes.

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 importance of oxygen in metabolism?

Back

Oxygen is crucial for aerobic respiration, which allows cells to efficiently produce energy from glucose.

Front

What happens if a person does not eat enough food?

Back

If a person does not eat enough food, their cells may lack the necessary molecules to produce energy, leading to fatigue and decreased physical performance.

Front

How does exercise affect metabolism?

Back

Exercise increases metabolism by raising the rate at which the body burns calories and uses energy.

Front

What is the role of enzymes in metabolism?

Back

Enzymes are proteins that speed up chemical reactions in the body, including those involved in metabolism.

Front

What is the relationship between metabolism and energy levels?

Back

Metabolism directly affects energy levels; a higher metabolic rate typically results in more energy available for physical activities.
