What Is the Most Efficient Enzyme Known That Can Catalyze Hydrogen?

catalase, an enzyme that brings about (catalyzes) the reaction by which hydrogen peroxide is decomposed to water and oxygen. Found extensively in organisms that live in the presence of oxygen, catalase prevents the accumulation of and protects cellular organelles and tissues from damage by peroxide, which is continuously produced by numerous metabolic reactions. In mammals, catalase is found predominantly in the liver.

What is the most efficient enzyme catalyze hydrogen?

Catalase (CAT, 1.11. 1.6) is an antioxidant enzyme present in all aerobic organisms. It is known to catalyze H 2 O 2 into water and oxygen in an energy-efficient manner in the cells exposed to environmental stress.

What is the most efficient enzyme known that can catalyze hydrogen group of answer choices?

The catalase enzyme is one of the most efficient enzymes known, since each enzyme can perform nearly 800,000 catalytic events per second. The key catalase function is protecting cells from hydrogen peroxide (H 2 O 2 ) molecules by converting them to oxygen (O 2 ) and water (H 2 O).

What enzyme can be detected using hydrogen peroxide?

In this case oxygen is generated when hydrogen peroxide breaks down into oxygen and water on contact with catalase, an enzyme found in liver.

What type of enzyme is catalase?

Peroxidases, also known as catalases, are also an oxidoreductase class of enzymes, which catalyze oxidoreduction reactions. The peroxidase enzyme catalyzes the decomposition of hydrogen peroxide into water and molecular oxygen (see illustration). Catalase is a haem-containing enzyme.

Have you ever wondered how all the food that you eat gets digested? It is not only the acid in your stomach that breaks down your foodmany little molecules in your body, called enzymes, help with that too. Enzymes are special types of proteins that speed up chemical reactions, such as the digestion of food in your stomach. In fact, there are thousands of different enzymes in your body that work around-the-clock to keep you healthy and active. In this science activity you will investigate one of these enzymes, called catalase, to find out how it helps to protect your body from damage.

Then, the reaction products are released from the pocket, and the enzyme is ready to start all over again with another substrate molecule. The reactions can include by-products such as hydrogen peroxide, which can be harmful to the body, just as how a by-product of a nice bonfire can be unwanted smoke that makes you cough or stings your eyes. To prevent such damage, the catalase enzyme helps getting rid of these compounds by breaking up hydrogen peroxide (H 2 O 2 ) into harmless water and oxygen.

Safety goggles or protective glasses Five teaspoons of dish soap One package of dry yeast Hydrogen peroxide, 3 percent (at least 100 mL) Three tablespoons One teaspoon Five 16-ounce disposable plastic cups Tap water Measuring cup Permanent marker Paper towel Workspace that can get wet (and won’t be damaged by any spilled hydrogen peroxide or food-colored water) Food coloring (optional) Try adding different amounts of yeast solution to three tablespoons of hydrogen peroxide, starting with one teaspoon. When the enzyme catalase comes into contact with its substrate, hydrogen peroxide, it starts breaking it down into water and oxygen.

However, the dish soap that you added to all your solutions is able to trap the gas bubbles, which results in the formation of a stable foam. As long as there is enzyme and hydrogen peroxide present in the solution, the reaction continues and foam is produced. If you do not add dish soap to the reaction, you will see bubbles generated but no stable foam formation.

Once you add more hydrogen peroxide to the solution, the reaction rate will increase as more substrate molecules can collide with the enzyme, forming more product. If the pH or temperature deviates from these conditions too much, the enzyme reaction slows down significantly or does not work at all. Cleanup Pour all the solutions into the sink and clean all the spoons with warm water and dish soap.

Wipe your work area with a wet paper towel and wash your hands with water and soap.
