Which one of these molecules MUST be broken down before our bodies can use them?

• Oxygen

• Amino Acids

• Carbohydrates

Answer explanation

Why are amino acids important for the body?

• Amino acids are used to create carbohydrates

• Amino acids are used to create oxygen and help heal and build the body.

• Amino acids are used to build protein and help heal and build the body.

• Amino acids are used to create energy

If someone has diabetes, they may feel tired. Why would someone feel tired if they have diabetes?

• Diabetes prevents cells from getting glucose that is used for cellular respiration.

• Diabetes prevents cells from getting enough oxygen that is used for cellular respiration.

• Diabetes lowers the number of red blood cells.

• Diabetes stops the body from making enzymes
