Factors That Affect The Rate Of An Enzyme

CONDITIONS AND FACTORS THAT AFFECT ENZYME ACTIVITY INTRODUCTION Catalase is an enzyme found in mammalian tissues and catalyzes the reaction by which hydrogen peroxide (H2O2) is decomposed into oxygen (O2) and water (H2O).(4) Enzyme activity and efficiency is affected by the conditions that the reaction occurs in. Changes in conditions can result in altering of the enzyme’s three dimensional shape and affect the enzyme’s function.(1) The conditions that influence the activity of an enzyme include pH…

Investigation in to the factors that affects the rate of fermentation of Glucose Aim: To investigate the factors that affects the rate of fermentation of Glucose. Background knowledge. ENZYMES Fermentation is a form of an anaerobic respiration where by glucose is partially broken down so only a small amount of energy is released. The yeast cells use the enzymes, ZYMASE to break down sugars unable to obtain. GLUCOSE CARBON DIOXIDE + ETHANOL(+ENERGY) C6 H12 O6 6CO2 + C2H5OH (210KJ) Enzymes have several…

The function of an enzyme is to speed up the rate of a chemical reaction by lowering the activation energy required to begin the reaction. Due to an enzyme 's ability to lower activation energy and speed up chemical reactions, they are often referred to as biological catalysts. Enzymes are large, protein molecules that are folded in such a way that only specific molecules, called substrates, can bind to them. The substrates bind to the enzyme at the active site, where the chemical reaction is catalyzed…

shorter than whites (Curry, 2010). When it came to robbery Hispanics had longer sentences than whites. The race of the offender showed on difference with sentencing in his study. He also found that the relationship between the victim and offender did affect the length of sentencing by having longer sentencing. The homicide victimization of a female that is white led to a sentence that was longer than any race of males (Curry, 2010). They had a 50% increase in sentence length, while Hispanics has 34%…

females that had careful attention and handling by the experimenters displayed an increase in OTR binding. The same results were reported in males. They concluded that the type of maintenance that pups received in early days after being born does affect receptor binding. In rats, the proper care is observed through licking and grooming. Therefore, early maternal behavior such as those increase the likelihood of receptor binding. On the other hand, maternal separation in male rats resulted in a decrease…

Introduction Each living cell has enzymes, which are catalysts that speed up reactions without being used up themselves (Barnhart and Hooper 2014). They work by lowering the activation energy, the amount of energy that must be overcome in order for the chemical reaction to take place (Barnhart and Hooper 2014). A chemical reaction is the action of taking one or more chemicals and rearranging them into a new chemical form. There are a few different factors that can affect the rate of chemical reactions. The…

List and describe the four factors that affect the rate of drug distribution. Absorption "The main factor which relates to absorption of drugs is the route of administration. Physiological considerations in absorption are blood flow, total surface area, time of arrival of the drug and time of drug at absorption site. Other considerations for absorption are solubility, chemical stability and how soluble the drug is in lipids". Distribution "Drugs are distributed into major body fluids (e.g. plasma)…

There are five main factors that affect that rate of a chemical reaction. These are the surface area of a solid reactant, the concentration and pressure of a reactant, temperature, the presence or absence of a catalyst and agitation. There is also another factor which is able to affect the rate which is the nature of the reactants. The surface area of a solid reactant can speed up a reaction. This is because if a physical change is made to the substance than the particles originally on the inside…

the reaction takes place. But there are other factors could affect the catalytic process, such as temperature, density, or pressure. Besides these factors, is there any other factor that could affect the efficiency of catalytic process? That triggers my interest of investigation. During agricultural use of catalyst, farmers try to change the pH value of fertilizer to control the amount of time seeds need to germinate . Does pH value of solution affect the catalytic efficiency? That becomes next step…

movements (Spotilia & Berman 1976). If amphibians become dehydrated, their oxygen consumption and metabolic state becomes at risk (Pough et al. 1983). As with movement rates, water loss rates are species specific. The northern leopard frog has a higher loss rate than the marine toad due to the northern leopard frog’s higher diffusion rate of water through their permeably skin (Bentley & Yorio 1976). Also, toads typically live a more terrestrial life than most frogs and therefore have developed mechanisms…
