INTRODUCTION Enzymes are a protein serving as a catalyst‚ a chemical agent that changes the rate of the reaction without being consumed by the reaction. Enzymes are proteins made up of long chains of amino acids. These form complex shapes. The enzymes are individuals‚ like the different players on a ball team‚ they have different specific structures and jobs. As one ball player may be very tall and one short‚ the specific different shape of the active site on an enzyme is unique and prepares it

The Determination of the Effect of pH on Amylase Activity Grace Chung Abstract: Amylase is an important enzyme in the human body as it allows for the consumption of starch by breaking the polysaccharide down into maltose units. All enzymes‚ including amylase‚ function best at a certain optimal pH. Therefore‚ in this experiment‚ the effect of different pHs on the reaction rate of amylase is studied. It was hypothesized that the amylase-starch reaction would proceed fastest at a pH closest to

Cardiovascular Endurance I did the 1 mile walk and my time was 17 minutes and 26 seconds. My heart rate at the end of my walk was 100 bpm. My VO2 max was a 48.72 and for my people are around my age that just ranked in the category of just good. I was not able to perform the 3 minute step test because of medical reasons. The benefits of the step test would be that there is not a lot of energy being exerted by the participants. Unlike running‚ stepping comes natural making this test less challenging

How Temperature Affects Amylase Activity Abstract This study of the effect of temperature on the enzyme amylase was performed to determine the relationship between the enzyme amylase and temperature. The rate of reaction was found to increase as the temperature of the environment was raised. As the temperature was raised from 5°C‚ 20°C‚ 35°C and finally to 80°C the rate of reaction followed this trend and also increased. However as predicted in the hypothesis of this experiment when the temperature

of that substance by titrating the sample with a solution of a strong oxidizing agent. In this lab‚ a solution of KMnO4‚ an oxidizing agent‚ will be standardized by titration with a solution containing a known concentration of iron (II) ions‚ (Fe+). The concentration of oxalic acid solution will be determined by titration with the MnO4- solution that had been standardized first. The purpose of this lab is to standardize a solution of potassium permanganate by redox titration with a standard solution

Lab Report (Effect of concentration on enzyme activity) Biology Noor Alawadhi 11- KC Introduction: An Enzyme is a protein‚ which is capable of starting a chemical reaction‚ which involves the formation or breakage of chemical bonds. A substrate is the surface or material on or from which an organism lives‚ grows‚ or obtains its nourishment. In this case it is hydrogen peroxide. This lab report will be explaining the experiment held to understand the effects of the changes in the amount of

Module 16 Notes Reduction/Oxidation Reactions • Oxidation number: The charge that an atom in a molecule would develop if the most electronegative atoms in the molecule took the shared electrons from the less electronegative atoms. • Oxidation numbers are not real; they are only based on assumptions. They are useful bookkeeping tools though‚ and can help us keep track of electrons during a reaction. • The sum of all oxidation numbers in a molecule must equal the charge of that molecule. • Rules
