Enzymes

that are the sources of the enzyme catalase. Although the hydrogen peroxide solutions were at the desired temperatures, it was uncertain whether their paired liver cubes had the same temperatures. This places concern on whether the froth height was close to being accurate, hence reliable. If the temperature of a liver were lower than the desired temperature, the enzymes would be less likely to collide to their substrates because according to Sam Adam-Day 2014, enzymes and substrate collide…

interacts with the hydrogen peroxide. The hydrogen peroxide is altered when two substances are combined. The oxygen gas, as a product, comes from the hydrogen peroxide. Enzymes are big proteins that speed up the rate of a chemical reaction by moving as a catalyst. A catalyst provides the environment for the reaction to occur. Catalase is an enzyme in the liver that breaks down dangerous hydrogen peroxide into water and oxygen. When this reaction takes place, oxygen gas bubbles breakout and…

An enzyme is a biological catalyst; catalysts are substances that increase the rate of chemical reactions without being used up. Enzymes also make the reaction take place more often, and are needed in small amounts; they are also neither reactants nor products. Enzymes are also proteins that are folded into complex shapes that allow molecules to fit into them. The enzymes that are involved in respiration, photosynthesis and protein synthesis work within cells whereas other enzymes are secreted…

Enzymes are true catylst that exist in the living matters, helping to speed up the reactions and to keep up the metabolisms within the cell. Enzymes will work properly when working in favorable condition and with substrates that will bind easliy to form products. Enzymes bind to specific sustrates for form specific product(s) in different parts of the cell. These happens in the active site where chemical reaction begain as substrates are binded to the enzymes. Enzymes have different shapes, bond…

Enzymes are organic catalysts that speed up reactions that occur by lowering the activation energy of the reactants. By lowering the activation energy, the chemical bonds are weakened, thus the reactions are much faster than without the catalyst. Enzymes are composed of proteins which shape dictates the function of the enzyme. On the enzyme it contains a part called the active site where the substrate binds and the chemical reaction undergoes. A substrate is the chemical involved in the…

experiment looks at the effects of pH, enzyme concentration, and temperature of the catalytic rate of different enzymes including alkaline phosphatase (ALP). Some of the enzymes used are involved in human digestion while others are involved in clinical tests for certain diseases (Wilson, D’Alessio, Schmitt Lavin, Keith, & BIOL 1500 Team, 2015). The ALP enzyme is used to diagnose diseases such as bone cancer, jaundice and cirrhosis of the liver. This enzyme also catalyzes the hydrolysis of a…

Enzymes are biological highly selective catalyst, greatly accelerating both the rate and specificity of metabolic chemical reactions, from the digestion of food to the synthesis of DNA. Enzymes catalyze chemical reactions involving the substrate. Substrate is a molecule that attach to the active site of the enzyme protein which an enzyme acts. Active site is a small port in an enzyme that helps enzyme to bind with substrates and undergo a chemical reaction. During this binding of substrates with…

Introduction Enzymes are specialized proteins present in all living organisms, whether animals, plants or microorganisms (Reece et al., 2012) .In addition, life would cease to exist without these vital organic molecules, as they are needed for metabolic processes, and other reactions and processes in the body (Reece et al., 2012). Sometimes some RNA molecules can act as enzymes (Reece et al., 2012). Enzymes as well as their substrates work best at optimal levels, and are affected by temperature…

Lactose is a sugar found in milk and milk products. Lactase Is an enzyme found in the small intestine that breaks down lactose into simple sugars such as glucose. The substrate has to fight to bind with the enzyme lactase. The inhibitor tries to attach to the lactase and slow down the chemical reaction while the substrate does the opposite. The substrate increases the rate of the chemical reaction, this chemical reaction breaks down the lactose into sugars. This chemical reaction is imperative…

The first enzyme to be inactivated by ultrasonic waves was pepsin about 60 years ago and the mechanism of inactivation was cavitations (Geckeler, 2009). Heat was the common method used in inactivation of enzymes, however, was observed to lower the quality of the preserved food as well as destroying food nutrients. Ultrasound is being tested as an alternative in enzymatic inactivation (Geckeler, 2009). Since 60 years ago ultrasound has been observed to be an efficient method in enzyme…
