Match each of the four biomolecules with its function (job) in your body...

Draggable emnearrow_right_altKorresponderende emne

Carbohydrates

arrow_right_alt

Provides your cells with the instructions they need to make their proteins.

Proteins

arrow_right_alt

Cells in your body metabolize (break down) this for a quick source of energy.

Nucleic Acids

arrow_right_alt

Used for long-term energy storage and insulation (keeps you warm).

Lipids

arrow_right_alt

Builds your physical traits (Hair, skin, nails, muscles, etc.). Enzymes are this biomolecule.

When people eat undercooked chicken, they are at risk for contracting salmonella poisoning, a disease caused by the Salmonella bacteria. Symptoms include diarrhea, fever, stomach cramps, nausea, vomiting, chills, headache, and blood in stool. The CDC advises cooking chicken to the proper internal temperature to kill the bacteria inside of the food and avoid getting sick.

Why does heating your chicken to the proper temperature kill the Salmonella bacteria?

Catecholase is an enzyme found in fruits such as apples, bananas, and avocados. When exposed to oxygen in the air, catecholase breaks down catechol and results in brown spots forming on the surface of fruits.

In an experiment, avocado was added into a test tube by itself, with water, and with lemon juice. The results of the experiment are shown below.

Test Tube C did not show any brown spots because the lemon juice .
