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 using energy).

Front

What role do enzymes play in metabolism?

Back

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

Front

What is the primary source of energy for cells?

Back

The primary source of energy for cells is glucose, which is derived from carbohydrates.

Front

Why is oxygen important for exercise?

Back

Oxygen is important for exercise because it is needed for cellular respiration to produce energy during physical activity.

Front

What can happen 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.

Front

What is the role of amino acids in metabolism?

Back

Amino acids are the building blocks of proteins and are essential for growth, repair, and energy production in the body.
