Amplify Unit 2: Metabolism Review

Front

What do all cells need to work properly?

Back

All cells need molecules from food and molecules from air to work properly.

Front

Why is it a problem if food is not broken down properly in the digestive system?

Back

If food is not broken down properly, molecules from the food will not be small enough to reach the cells, affecting their function.

Front

What happens if a person does not eat enough food?

Back

If a person does not eat enough food, their cells will not get the necessary molecules from food and air to function properly.

Front

What is the role of glucose in cellular respiration?

Back

Glucose reacts with oxygen to release energy that cells need to function.

Front

What can low levels of glucose in cells indicate?

Back

Low levels of glucose in cells can indicate that the body may not have enough energy to perform activities, leading to fatigue.

Front

What is the relationship between starch and glucose?

Back

Starch is broken down into glucose molecules during digestion, which can then be used for energy.

Front

How does the respiratory system contribute to exercise?

Back

The respiratory system provides oxygen, which is necessary for cells to combine with glucose to release energy during exercise.

Front

What might indicate a problem with the respiratory system?

Back

If a person has enough glucose but low levels of oxygen in their cells, it may indicate a problem with the respiratory system.

Front

What is metabolism?

Back

Metabolism is the set of life-sustaining chemical reactions in organisms that convert food into energy.

Front

Why is oxygen important for cellular respiration?

Back

Oxygen is important because it is needed to react with glucose to release energy for the cells.
