Enzymes Enzymes are the sparks that start the essential chemical reactions our bodies need to live. They are necessary for digesting food‚ for stimulating the brain‚ for providing cellular energy‚ and for repairing all tissues‚ organs‚ and cells. There are three types of enzymes: metabolic enzymes‚ digestive enzymes‚ and food enzymes. Metabolic enzymes catalyse‚ or spark‚ the reactions within the cells. The body’s organs‚ tissues and cells are run by metabolic enzymes. Without them our bodies

Enzymes What Are Enzymes? Substances that speed up chemical reactions are called catalysts. Organic catalysts are called enzymes. Enzymes are specific for one particular reaction or group of related reactions. Many reactions cannot occur without the correct enzyme present. They are often named by adding "ase" to the name of the substrate. Example: Dehydrogenases are enzymes that remove hydrogen. Induced-fit Theory The shape of the enzyme must match the shape of the substrate

temperature on the activity of lipase Aim: To investigate the effects of temperature on the activity of lipase enzyme on milk which contain fats or lipids. Introduction: Enzyme is a kind of biological catalyst that made up of protein. It can speed up the metabolic reactions on various kinds of substances. Like lipase can break down lipid into glycerol or fatty acids in milk. Since enzyme is made up of protein which easily affected by varies temperature. This experiment is carried out to find the

Task 1 Look at Ur’s list of patterns of interaction below. Decide whether each interaction is either more student-centred or more teacher-centred. Justify your answers. Group work Student- Centered‚ because the main purpose of this is to let students interact among themselves and the teacher’s role is to monitor them throughout the activity. Closed-ended teacher questioning Teacher- Centered.since there is a expected or unique answer that the teacher wants to hear‚ the teacher is the instructor

Enzymes are responsible for multiple reactions that take place naturally in the living organisms. The purpose of the enzymes lab was to investigate how the enzymes play a role in a reaction‚ affecting the rate of reaction (ROR). Interestingly‚ we tested how the enzymes affect the reaction rate at multiple temperatures (0‚ 23‚ 37‚ 50‚ 70‚ and 95 C). It was predicted that an increase in temperature will elevate the thermal activity of substrate which increases the chances the substrate molecules will

Investigation on the effects of Temperature‚ pH levels‚ and Enzyme Concentration on the reaction rate of the Decomposition of Hydrogen Peroxide by Catalase The purpose of this investigation is to figure out how temperature‚ pH‚ and enzyme concentration affect the reaction rate of an enzyme. It’s important to understand how certain factors affect enzymes because of their crucial role in the metabolic processes of life. Enzymes lower the activation energy necessary for a chemical reaction to

Essay on Social Interaction – Social interaction is the foundation of society. It is the very essence of social life. Hence‚ the concept is crucial to any study of the dynamics of society and culture. Without interaction there would be no group life. Mere presence of individuals in a place does not weld them into a social unit or group. It is when persons or groups of persons do such things as work or play or talk together with common end‚ or when they compete or quarrel with each other that group

Purpose: The purpose of this lab was to observe and understand the effects of changes in temperature‚ pH‚ enzyme concentration‚ and substrate concentration on the reaction rate of an enzyme-catalyzed reaction. Another purpose of the lab was to explain how environmental factors affect the rate of enzyme-catalyzed reactions. Hypothesis: I believe that if there is an increase in enzyme concentration‚ an increase in temperature‚ or an increase in pH‚ then the intensity of the reaction will increase

Varibles that affect Enzyme Catalysis Reaction Rates Introduction Molecules are constantly moving in our bodies and in nature. When molecules move fast enough they collide into one another‚ allowing chemical reactions to occur. Factors such as temperature and concentrations can either help increase or decrease these reactions. (Jubenville.) Enzymes are known as catalyst because they are able to speed up reaction rates without being destroyed or altered. They are able to encourage chemical reactions
