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 to store energy).

Why is glucose important for cellular energy?

Back

Glucose is a simple sugar that is a primary energy source for cells; it is broken down during cellular respiration to produce ATP, the energy currency of the cell.

Front

What role does oxygen play in metabolism?

Back

Oxygen is essential for aerobic respiration, a process that allows cells to efficiently convert glucose into energy (ATP) with the release of carbon dioxide and water.

Front

What happens during digestion?

Back

During digestion, food is broken down into smaller molecules (like glucose and amino acids) that can be absorbed into the bloodstream and used by cells.

Front

What is the function of the digestive system?

Back

The digestive system breaks down food into nutrients, which are then absorbed into the body to provide energy and support growth.

Front

What is the role of the respiratory system in metabolism?

Back

The respiratory system supplies oxygen to the body and removes carbon dioxide, which is crucial for cellular respiration and energy production.

Front

How do cells use glucose?

Back

Cells use glucose in a process called glycolysis, where it is broken down to produce ATP, which powers various cellular activities.

Front

What is ATP?

Back

ATP (adenosine triphosphate) is the energy currency of the cell, providing energy for many cellular processes.

Front

What is the relationship between metabolism and exercise?

Back

Metabolism provides the energy required for exercise; efficient metabolism ensures that muscles receive enough energy to perform physical activities.
