Metabolism

Front

What is metabolism?

Back

Metabolism is the set of life-sustaining chemical reactions in organisms that convert food into energy and building blocks for growth.

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).

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 do cells obtain oxygen for metabolism?

Back

Cells obtain oxygen through respiration, where oxygen is inhaled and transported to cells via the bloodstream.

Front

What is the relationship between glucose and oxygen in cellular respiration?

Back

In cellular respiration, glucose reacts with oxygen to produce energy (ATP), carbon dioxide, and water.

Front

What are amino acids and why are they important?

Back

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

Front

What happens if a person does not get enough glucose?

Back

If a person does not get enough glucose, their cells may not have enough energy to function properly, leading to fatigue and weakness.

Front

What is the function of the digestive system in metabolism?

Back

The digestive system breaks down food into smaller molecules (like glucose and amino acids) that can be absorbed and used by the body.

Front

What is the significance of oxygen in metabolism?

Back

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