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 processes of metabolism?

Back

The two main processes of metabolism are catabolism (breaking down molecules to release energy) and anabolism (building up molecules using energy).

Front

What is the role of glucose in cellular respiration?

Back

Glucose is a simple sugar that is broken down in cells to produce energy, carbon dioxide, and water.

Front

How do cells obtain energy from food?

Back

Cells obtain energy from food through a process called cellular respiration, where glucose reacts with oxygen.

Front

What is the importance of oxygen in metabolism?

Back

Oxygen is essential for aerobic respiration, which is the process that generates the most energy from glucose.

Front

What happens to starch in the digestive system?

Back

Starch is broken down into glucose molecules by enzymes in the digestive system.

Front

Why might a person feel tired if their glucose levels are low?

Back

Low glucose levels mean that the cells do not have enough energy to function properly, leading to fatigue.

Front

What is the relationship between oxygen and glucose in energy production?

Back

Oxygen and glucose react together in cells to produce energy, carbon dioxide, and water during cellular respiration.

Front

What can happen if a person's digestive system is not functioning properly?

Back

If the digestive system is not functioning properly, the body may not break down food into glucose, leading to low energy levels.

Front

What is anaerobic respiration?

Back

Anaerobic respiration is a type of respiration that occurs without oxygen, producing less energy and resulting in byproducts like lactic acid.
