Enzyme is a type of protein that speed up the rate of reaction of living organisms. Enzyme also acts as a catalyst for specific chemical reaction by converting a specific reactants into a specific product. The enzyme activity will also be affected by temperature and pH value. In this experiment‚ enzyme was placed in carbohydrate solution at different temperature to identify unknown carbohydrate solution. The enzyme that involved in the reaction is salivary amylase. The action of amylase on starch

you agree? Explain. Q18: John Jamail says that he doesn’t understandwhy companies have labor price variances because most union contractsor other binding agreements set wage rates that do not normally change in the short term. How could rate variances occur even when binding commitments hold the dollar per hour rate constant? Chapter 9: 1‚ 4‚ 6‚ 13 Q1: Pam Kelly says she has no faith in budgets‚ Her company‚ Kelly Manufacturing Corporation‚ spent thousands of dollars to

The effect of molecular weight on the rate of diffusion was assessed using agar-water gel test. The agar-water gel set up was composed of a petri dish of agar-water gel containing three wells. Drops of potassium permanganate (KMnO4)‚ potassium dichromate (K2Cr2O7) and methylene blue(C16H18N3SCl) were simultaneously introduced to each well. Methylene blue‚ having the largest molecular weight‚ displayed the smallest diameter (11 mm) and diffused at the slowest rate (0.20 mm/min.). Next is potassium dichromate

of reactions observed shall determine the nature of these reactions: physical or chemical. Introduction: An elements¡¦ reaction to certain substances may be predicted by its placement on the Periodic Table of Elements. Across a period‚ an element on the left will react with more vigor than one on the right‚ of the same period. Vertically‚ as elements are sectioned into groups‚ the reaction of each element increases as you move down in the same group. With this in mind‚ the reactions of

Science Fair Research Paper My Science Fair topic is about silly putty and how it is made. Chemical reaction‚is the process by which one or more substances are converted into one or more different substances.Old bonds break and new bonds form. The original substances are called reactants. The resulting substances are called products. It is a simple chemical reaction. Another simple reaction might involve a reactant molecule breaking apart. Many enduring substances such as rock and water are highly

Conclusion: The result matches the prediction‚ as the height of the ramp increase‚ the speed of the toy car roll down on the ramp will increase because of the gravitational force pull the toy car down on the ramp‚ the higher height the toy car roll down on the ramp‚ the more gravitational forces involved‚ so the toy car will get a faster speed‚ but in the contrary‚ the lower height the toy car roll down on the ramp‚ there is less gravitational force‚ that’s mean the toy car will get a slower speed

Introduction: According to chemists‚ hydrolysis is defined as the breaking of a compound involving a reaction with a water molecule. The goal of this experiment is to three-dimensionally show how disaccharides are transformed into monosaccharides using an acid-catalyzed hydrolysis reaction. For the purpose of this lab‚ it is quite useful to fully understand the following terms: optical rotation and carbohydrate. Optical rotation is measured by a polarimeter‚ which measures the polarization of light

Structure: Enzymes are globular proteins that act as catalysts‚ they have a specific 3D shape that is the result of their amino acid sequence. There is a specific region of the enzyme that is functional‚ this is called the active site. The active site is made up of a small number of amino acids and forms a small depression within the larger enzyme molecule. Moreover‚ the molecule that the enzyme acts upon (substrate) fits precisely into the depression and forms an enzyme-substrate complex. The substrate

first know what the Kinetic Molecular Theory is. In our textbook is says it is “A simple model for gases that predicts the behavior of most gases under many conditions.” First off‚ we will take a look at Boyle’s Law. As stated in our lab manual “at constant temperature the pressure which a given mass of a gas exerts is inversely relate to its volume: P= k 1/V or PV= k.” The way the Kinetic Molecular Theory explains Boyle’s Law is that gases can be compacted because almost all of the volume of a gas
