Metabolism

Front

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 using energy).

Front

Why do cells need oxygen?

Back

Cells need oxygen to perform cellular respiration, which is the process that converts glucose into 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

How does the digestive system contribute to metabolism?

Back

The digestive system breaks down food into smaller molecules, such as glucose, that can be absorbed and used by the body for energy.

Front

What happens if the respiratory system is not functioning properly?

Back

If the respiratory system is not functioning properly, cells may not receive enough oxygen, leading to fatigue and decreased energy production.

Front

What is the relationship between food intake and energy levels?

Back

Food intake provides the necessary nutrients and energy for the body to function; insufficient intake can lead to low energy levels.

Front

How do muscles use energy during exercise?

Back

Muscles use energy from glucose and oxygen to contract and perform work during exercise.

Front

What is cellular respiration?

Back

Cellular respiration is the process by which cells convert glucose and oxygen into energy, carbon dioxide, and water.
