Metabolism Review

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 processes of metabolism?

Back

The two main processes 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, making metabolism more efficient.

Front

What is the primary function of the respiratory system?

Back

The primary function of the respiratory system is to bring oxygen into the body and remove carbon dioxide.

Front

Why is oxygen important for cellular respiration?

Back

Oxygen is essential for cellular respiration because it helps convert glucose into energy (ATP) in the presence of oxygen.

Front

What are amino acids?

Back

Amino acids are the building blocks of proteins, which are essential for growth, repair, and overall body function.

Front

How do cells obtain energy from food?

Back

Cells obtain energy from food through a process called cellular respiration, where glucose is broken down with oxygen to produce energy.

Front

What happens if the digestive system is not functioning properly?

Back

If the digestive system is not functioning properly, nutrients from food may not be broken down and absorbed, leading to energy deficits.

Front

What is the relationship between the respiratory and circulatory systems?

Back

The respiratory system brings oxygen into the lungs, and the circulatory system transports that oxygen to cells throughout the body.

Front

What is the role of glucose in metabolism?

Back

Glucose is a primary source of energy for cells and is used in cellular respiration to produce ATP.
