Meat tenderizer has an enzyme called papain, which breaks down long chains of proteins, like the ones found in Jell-O. Papain was added to three different test tubes with Jell-O. Each test tube was then placed in a water bath for ten minutes. The data collected during the experiment is shown below.
Which statement best explains the results of test tube 3?
The complex carbohydrates pictured below are made by linking molecules of glucose. In all three complex carbohydrates, the subunits of glucose are bonded together differently. Because they have different structures, they most likely:
The terms listed below describe functions and examples of carbohydrates and lipids. Select whether each statement applies to carbohydrates, lipids, or both.

What is the purpose of an enzyme?
Complete the sentence below.
A change in can cause the enzyme to change shape and denature, so it .
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 , resulting in .
