Metabolism Practice Test

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 for energy) and anabolism (building up molecules for growth and repair).

Front

What is cellular respiration?

Back

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

Front

What is the role of glucose in the human body?

Back

Glucose is a primary source of energy for the body's cells.

Front

What are amino acids?

Back

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

Front

What system transports nutrients like glucose and amino acids in the body?

Back

The circulatory system transports nutrients, oxygen, and waste products throughout the body.

Front

What is the significance of oxygen in cellular respiration?

Back

Oxygen is essential for cellular respiration as it helps to release energy from glucose.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants use sunlight to convert carbon dioxide and water into glucose and oxygen.

Front

What is the difference between digestion and cellular respiration?

Back

Digestion is the breakdown of food into smaller molecules, while cellular respiration is the process of converting those molecules into energy.

Front

What is homeostasis?

Back

Homeostasis is the process by which living organisms maintain a stable internal environment despite changes in external conditions.
