Exploring Two Enzymes: Catalase And Breaks

In Lab 4 You Are Exploring Two Enzymes Catalase That Breaks Down Hydr

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. 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? Any other products you use 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. Explain how this enzyme is used. What is the substrate in the chemical reaction? And what is the product(s)? Remember that a chemical reaction 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! Your main response should be at least 300 words and include references to all information sources used. PLEASE INCLUDE TWO RESPONSES TO STUDENTS!!!!!

Enzymes are biological catalysts that facilitate specific biochemical reactions within living organisms and find extensive applications in industry and everyday products. Among the widely recognized enzymes are catalase and amylase. Catalase accelerates the breakdown of hydrogen peroxide—a potentially harmful byproduct of cellular metabolism—into water and oxygen, thus protecting cells from oxidative damage (Nelson & Cox, 2017). Amylase, on the other hand, catalyzes the hydrolysis of starch into simpler sugars such as maltose and glucose, playing a crucial role in digestion (Nelson & Cox, 2017). Beyond their biological functions, enzymes are incorporated into various commercial products, notably in cleaning agents, food processing, and industrial applications, due to their specificity and efficiency.

Many household cleaning products contain enzymes, primarily proteases, lipases, and amylases. Proteases break down protein-based stains like blood and grass, lipases target fat and grease, and amylases help in removing starchy residues. For example, certain laundry detergents list enzymes as ingredients to enhance stain removal; they specify the type of enzyme used, such as amylases or proteases. These enzymes are sourced from microorganisms like bacteria and fungi—most notably Bacillus species (Kong & Li, 2012). In industry, enzymes such as cellulose and pectinases are employed to process textiles and produce fruit juices, respectively.

In the food industry, enzymes are used to improve manufacturing efficiency and food quality. For instance, invertase (also known as β-fructofuranosidase) catalyzes the hydrolysis of sucrose into glucose and fructose, which is vital in confectionery and soft drink production (Kashyap et al., 2001). This enzyme’s substrate is sucrose, and the products are glucose and fructose, which have different properties beneficial for manufacturing. In baking, amylase enzymes convert starches into fermentable sugars, aiding yeast fermentation, and improving bread texture.

Focusing on industrial and cleaning applications, the enzyme bromelain, derived from pineapple stems, exemplifies a protease used in meat tenderizers and pharmaceuticals. Bromelain catalyzes the breakdown of protein substrates such as collagen, making it useful in medical wound debridement and in tenderizing meat (Maurer, 2001). Its mechanism involves cleaving peptide bonds within protein molecules, with the substrate being proteins like collagen and the products being smaller peptide chains and amino acids.

In conclusion, enzymes such as amylase, proteases, and bromelain are integral in various sectors. Their substrate specificity ensures targeted reactions, which enhance efficiency and sustainability across industries. Understanding enzymatic functions helps in optimizing their use in cleaning, food production, and industry.
