Metabolism - Chapter 1 Checkpoint

Metabolism

By Mr. Weaver

​The body takes in molecules from food and from the air.

The food molecules enter our body and pass through the mouth and stomach as starches and proteins.

These molecules are too big, and must be broken down in the small intestines into their smaller molecules - glucose & amino acids.

Multiple Choice

Is this model correct?

• Yes - it shows exactly the molecules that the cell needs to function.

• No - there are errors, this cell would not have exactly what it needs to function.

Multiple Choice

Is this model correct?

• Yes - it shows exactly the molecules that the cell needs to function.

• No - there are errors, this cell would not have exactly what it needs to function.

Multiple Select

What are the errors in this picture? Select 2.

• The cell is shown with proteins and amino acids, which are too big to enter the cell.

• The cell is shown with oxygen, which cannot enter the cell.

• The cell is shown without glucose, which is needed.

• The cell is shown without water, which it needs.

​The body takes in molecules from food and from the air.

The oxygen molecules from the air are passed on from the lungs to the blood, and sent into the cells.

Multiple Choice

How do our bodies get the glucose, amino acids, and oxygen molecules that our cells need?

• We get oxygen from the food that we eat, and glucose & amino acids from the air we breathe in.

• We get glucose & amino acids from the food that we eat, and oxygen from the air we breathe in.

Elisa feels tired all of the time.
Remember that healthy cells need three things?

Elisa's body cells only contain oxygen and amino acids.

Elisa's cells do not have enough glucose.

Multiple Choice

What are the three molecules that cells need to produce energy?

• glucose, amino acids, water

• oxygen. glucose, water

• amino acids, glucose, oxygen

• oxygen, water, amino acids

Multiple Choice

Where does the body get glucose and amino acid molecules from?

• from the air

• it makes them

• from food

Multiple Choice

Where does the body get oxygen molecules from?

• food

• air

• doctor

• circulatory system

Multiple Choice

Where does the body get oxygen molecules from?

• from the air

• it makes them

• from food

​This picture shows a healthy cell, that has exactly what it needs to generate the energy it needs to function:

glucose

oxygen

amino acids

Multiple Choice

What does Elisa feel tired all of the time?

• She is not getting enough sleep.

• She is not eating the right foods - she needs to change her diet.

• Her cells are not getting all of the molecules that they need.

Multiple Choice

What are Elisa's cells not getting enough of?

• amino acids

• oxygen

• glucose
