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. Enzymes work within a small ph range, therefore ph levels tend to have a great impact on the enzyme-substrate activity (nelson biology 12) any ph level above or below 7 started to denature the enzyme, slowing down the rate of reaction. This experiment is designed to analyze how does the enzyme catalase activity gets affected by the ph levels the experiment has also been designed to outline all the directions and the ways by which the observation can be made clearly and to accurately.

The chemical structure of an enzyme relates to the catalytic activity because the active site, a small pocket on the surface if the enzyme, triggers the catalytic process this is when a substrate occupies an active site and attaches by weak bonds. Modifiers of enzyme activity: like all mammalian proteins, enzymes are degraded to amino acids although this mechanism reduces enzyme concentration and, hence, catalytic activity, still they are slow, wasteful of carbon and energy and, rather, they are like turning out a light by smashing the bulb, then inserting a new one when light is needed.
Bio ia ensymes essay 2000 words - 8 pages concentration of enzyme amylase) on rate of reaction of amylase, on the hydrolysis of starch into maltose introduction enzymes are biological catalysts that catalyze biochemical reactions in living cells. enzyme activity conclusion explanation #3 states that the substance in the potato that interacts with hydrogen peroxide is altered when the two substances are mixed the oxygen gas, as a result, comes from both the hydrogen peroxide and the substance in the potato. In conclusion, enzyme catalase exhibits low activity at low temperatures (05°c) and high temperatures (612°c) its activity is the greatest at around 35°c the experimental set-up was generally satisfactory to minimize errors except of some defects such as the methodology in measuring the rate of the reaction.
Welcome anti essays offers essay examples to help students with their essay writing our collection includes thousands of sample research papers so you can find almost any essay you want. The consequence of concentration on enzyme activity it can be noted that both enzyme solution used had different consequences enzyme activity was greater when utilizing the poulet liver instead than the cow liver.
The effect of ph on enzyme activity essay - the effect of ph on enzyme activity ph is a measure of the concentration of hydrogen ions in a solution. In conclusion, our hypothesis was supported because it was found that ph 70 is the optimal temperature for the enzyme amylase and phs lower or higher than that would result in slower reaction rates it was noticed that the graph of time of reaction completions vs ph was not entirely symmetrical. Finally, the enzyme concentration activity was observed by taking three test tubes and adding 1 ml of starch solution ph 7 to each tube added to tube 1 was 50µl of the 5% enzyme tube 2 obtained 50µl of the 10% enzyme and tube three obtained 50µl of the 20% enzyme. The effect of ph on the activity of the enzyme amylase aim :-to find the effect of ph on the activity of the enzyme amylase an enzyme is a type of protein found in all living cells. Scientific methodology & enzyme activity essay laboratory 2: scientific methodology & enzyme activity objective: the purpose of this experiment was to simply measure oxygen production rates released from decomposed hydrogen peroxide under different conditions (concentration of enzymes, temperature, and ph level.
Enzyme activity lab discussion conclusion essays and research papers enzyme activity lab discussion conclusion sample lab report: factors which affect the activity of the enzyme catalase purpose: must include: background information about concepts involved in the lab , statement of purpose of the lab identification of independent and dependent variables. Or in other words, it is ok to use the same enzyme/subtrate/method as you did in lab 4 (but modify the treatment), or you can search on-line to find a different enzyme/subtrate/method for measuring enzyme activity. The activity of the enzyme in relation to the total protein present (ie the specific activity) can be determined and used as a measure of enzyme purity a variety of methods can be used to remove contaminating material in order to purify the enzyme and increase its specific activity. The enzyme catalase is present in cells in order to speed the breakdown of hydrogen peroxide (h2o2), which is a toxic chemical to the human body when hydrogen peroxide is broken down, the end products are water (h2o) and oxygen (o2.
activity of the enzyme catalase in breaking down hydrogen peroxide and the effect of various factors on enzyme activity introduction the enzyme catalase is present in cells in order to speed the breakdown of hydrogen peroxide (h2o2), which is a toxic chemical to the human body when hydrogen peroxide is broken down, the end products are. Part a - effect of temperature on rennin intro temperature affects the rate at which molecules collide with each other an increase in temperature will inturn increase activity and rate of reacton.
Essay about investigating enzyme activity - investigating enzyme activity aim: to investigate how the concentration of hydrogen peroxide effects the rate of reaction of an enzyme (catalase) variables: these factors could effect the rate of reaction on an enzyme: ph concentration temperature surface area ph - enzymes function at different ph values. Temperature on enzyme activity aim: to determine the effect of temperature on enzyme activity introduction: enzymes are biological catalysts which are made up of protein a catalyst is a kind of substance that alters the rate of chemical reaction without being altered itself. The essays should be several paragraphs in length for each question, be thoroughly paraphrased, and include appropriate in-text citations and a reference list in apa format how is enzyme activity regulated by the cell.
