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 glucose molecules play in metabolism?

Back

Glucose molecules are a primary source of energy for cells, used in cellular respiration to produce ATP.

Front

Why is oxygen important for cellular respiration?

Back

Oxygen is essential for cellular respiration as it helps to break down glucose, releasing energy in the form of ATP.

Front

What happens if there is not enough oxygen in the body?

Back

If there is not enough oxygen, cells cannot efficiently produce energy, leading to fatigue and decreased physical performance.

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

How do starch molecules contribute to energy production?

Back

Starch molecules are broken down into glucose during digestion, which can then be used in cellular respiration to produce energy.

Front

What is the relationship between food intake and energy levels?

Back

Food intake provides the necessary molecules for metabolism; insufficient intake can lead to low energy levels and fatigue.

Front

What is the significance of amino acids in metabolism?

Back

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

Front

How does the respiratory system support metabolism?

Back

The respiratory system supplies oxygen to the blood, which is then delivered to cells for energy production during metabolism.
