Enzyme Essay Examples

Rate of reaction

Apart from these few improvements I think the equipment and the method I used was an appropriate way of investigating how concentration effects the rate of reaction on an enzyme. A variable that I could try for an extra experiment is temperature. I could try increasing the temperature of the catalase to see if increasing… View Article

Effect of Varying Temperatures on Enzymatic Activity

Abstract This experiment consisted of setting up a control group of starch in various temperature and then placing both fungal amylases and bacterial amylases in a mixture of starch and placing the solution of amylase and starch in various temperatures of water. After a certain amount of time- different amount of time needs to be… View Article

Fundamentals of Cell Biology

The name of enzyme involved in this experiment is salivary amylase, which presents in our saliva. Salivary amylase catalyses the breakdown of complex sugar, such as starch, into a simple sugar, such as glucose. In this experiment, the optimum temperature for salivary amylase to function is 37˚C. Above the optimum temperature, the kinetic energy in… View Article

Human anatomy and Physiology

1. Ketones are formed by the breakdown of which substances? Fats for energy a process called ketosis 2. Hyperglycemia stimulates the secretion of which substance from the pancreas? Insulin 3. Hypoglycemia stimulates the secretion of which substance from the pancreas? Glucagon 4. What type of assay was used to measure plasma glucose and ketone levels?… View Article

Enzymology and Catalytic Mechanism

Many diseases and disorders are caused by defects in the molecular level of cells and not just having to do with nutrition or other extrinsic factors ,in this report ,we will specifically look at enzymes and their key role in energy production and the cycles and series of activities that make it possible for the… View Article

Biochemical Basis of HFI

1. 2 Important Features of Enzymes Enzymes are proteins used in chemical reactions. In the reactions, enzymes act as catalysts. They function to speed up chemical reactions without using the enzymes themselves. The catalysts are neither the reactor nor the product. The first feature discussed in the text is the energy of the reaction. Catalysts… View Article

Zachary’s Story

A) An ulcer starts by eroding the mucosa of the GI tract wall. What functions of digestion and/or reabsorption might be lost if this layer is no longer functional? What functions will be compromised if the ulcer eats through the submucosa and then the muscularis? Some of the ingested and secreted may not be absorbed… View Article

Banana Peel as an alternative for a shoe polish

I. Rationale Banana is a staple starch for many tropical populations.Depending upon cultivar and ripeness, the flesh can vary in taste from starchy to sweet, and texture from firm to mushy. Bananas are an excellent source of vitamin B6 and contain moderate amounts of vitamin C, manganese and dietary fiber. There many uses of the… View Article

Enzyme activities

The term “photosynthesis” is so called because it synthetic process driven by light. Many studies have been carried on the light spectrum quality, intensity, wavelength and their combinations thereof on the rates of photosynthesis. Different importances have been attributed to different factors. But light and carbon dioxide are the most important paramers for active photosynthesis…. View Article

The Influence of pH on the Activity of Catalase Enzyme

INTRODUCTION Enzymes are vitally important for every living organism, because without them the reactions within the cells would occur to slow to sustain life. However there are many factors which affect the rate of enzymes reactions. One of them is pH, which influence on the enzyme activity will be the subject of this investigation. Catalase… View Article

Biology: Experiment

Aim: The aim of the experiment is to test the effect temperature has on the activity of the enzyme rennin. Hypothesis: I believe the rate of reaction will speed up as the temperature increases until it reaches about 37oC, which is the body temperature, where it will begin to slow down and stop reacting. I… View Article

Alkaline Phosphatase

The Effects of varying p-Nitrophenyl Phosphate concentrations on Alkaline Phosphatase Activity Nathan Overholt Louis Settembrino March 5, 2002 Abstract: The enzyme Alkaline Phosphatase was set up in solutions of varying p-nitrophenyl phosphate concentrations. A fixed time assay was used to find the Michaelis constant and Vmax. All solutions were incubated at 30 C° for 30… View Article

Enzyme and Heavy Metals

These heavy metals are toxic to life because they generally bind tightly and permanently to the active sites of enzymes, thus destroying their catalytic properties and deactivating them (permanently). This therefore restricts substrates being broken down by enzymes to allow the human body to function properly since the heavy metals take similar pathways to that… View Article

The Iodine Test sor Starch

The purpose of this experiment was to use Iodine, Benedict and Biuret to test the reaction of the following 12 samples: 1% glucose, 0. 3% glucose-1-phosphate, 1% maltose, honey, 1% sucrose, 1%lactose, 1% glycogen, 1% starch, protein, beer, distilled water and an unknown solution (test tube: 300). The iodine test for starch was to test… View Article

Why doesn’t jelly set when fresh pineapple is used?

Basic Problem: Jelly is made from protein, gelatin, this is dissolved in hot water and as it cools, it sets. For a childrens party it was decided to make some fruit jellies, these were made by putting sliced pineapple into the jelly before it set, the following observations were made: oThe jelly set normally when… View Article
