Week 4 discussion

In lab 4 you are exploring two enzymes, catalase that breaks down hydrogen peroxide into water and oxygen, and amylase that aids in starch digestion. These are two examples of the many enzymes found inside our bodies, and many thousands (possibly millions) of similar and very different enzymes are found throughout all living organisms.

Enzymes are also used in many of the products we use. Check your cleaning supplies at home, do any of them list enzymes on the ingredient list? If so, does it say which type of enzyme? If not, complete online research to find examples of cleaning products that do contain enzymes. Are there any other products you use that contain enzymes? What type of enzymes are used in industry? Which enzymes are found in the food we eat?

After doing some research, choose and describe one enzyme that is used in cleaning products, other products, industrial procedures or that is found in food.

(1) Explain how this enzyme is used.

(2) What is the substrate in the chemical reaction catalyzed by your enzyme?

(3) And what are the product(s)?

Remember that a chemical reaction catalyzed by an enzyme converts one or more substrates to one or more products, and that most enzymes are substrate specific. When looking for enzymes remember that their names end with -ase.

You main response should be at least 150 words and include references to all information sources used.

You also need to post at least two 150+ word replies to the posts of other students. As part of your reply search for and share a video, tutorial or web-site that helps you and your classmates' better understand enzymes.
