    peroxide concentration on enzyme catalase Indroduction: Enzymes are proteins. They function as biological catalysts. They lower the energy barrier of a reaction so that the reaction can take place at body temperature. Also‚ they can speed up Metabolic reactions without being changed or used up. During a reaction‚ an enzyme molecule combines temporarily with the substrate. When the reaction is complete‚ the enzyme molecules returns to its original dorm and the product is released. So enzymes are never

    How Enzyme Concentration can Affect Rate of Reaction The purpose of this investigation was to see how the concentration of an enzyme affected the rate at which a substance was broken down. We did this by using a white protein called casein. Casein is found in milk powder‚ it is a protein and used mainly as a binding agent in foods‚ because it is mad to proteins and joins to a phosphoric acid it belong to a group called the phophoproteins. In terms of in milk it is said to be healthier if it is

    temperature on amylase activity Introduction Amylase is an enzyme that catalyses the breakdown of starch into sugars. Amylases are found in almost all plants‚ animals and microorganisms. Large amounts of amylase occur in germinating cereals‚ and in the pancreas and saliva of higher animals. Aim The aim of this experiment is to find out the rate of reaction between amylase and starch in a range of different reaction temperatures. Hypothesis As the reaction temperature of amylase solution

    Resistant starch (RS) is starch and starch degradation products that escape from digestion in the small intestine of healthy individuals.[1] Resistant starch is considered the third type of dietary fiber‚ as it can deliver some of the benefits of insoluble fiber and some of the benefits of soluble fiber. Some carbohydrates‚ such as sugars and most starch‚ are rapidly digested and absorbed as glucose into the body through the small intestine and subsequently used for short-term energy needs or stored

    Initial Thread In lesson 3‚ the presenter discussed Neil Postman’s article‚ "The Disappearance of Childhood". I agree that electronic media‚ such as television fails to show children in their place. Children are exhibiting various behaviors that do not represent God and what he wants for his people. The presentation states‚ according to Postman‚ "When literature disappears‚ education disappears. When education disappears‚ shame disappears." Children are no longer shameful of their actions
