Enzymes Ashley Njeru Mrs. Booth Tuesday‚ March 19th 2013 SBI 4U INTRODUCTION: The cellular activity of all organisms is controlled through the use of enzymes. An enzyme is a special type of biological molecule‚ usually a protein‚ which speeds up a chemical reaction; most are soluble in water or a dilute salt solution. There are about 4000 different enzymes in a typical living cell. If even one of these enzymes is missing or

In this enzyme lab‚ (insert creative name)‚ the enzyme catalase was observed under varying conditions in order to interpret what prohibits and inhibits the functioning of certain enzymes in chemical reactions. Enzymes aid in chemical reactions by speeding up the time it takes for the reaction to occur‚ without getting “used up” throughout the process. Catalase‚ the specific enzyme used in this lab‚ is a protein abundant in the liver and red blood cells. It enhances the breakdown of hydrogen peroxide

How free were free blacks in the North? Free blacks weren’t completely free at all. They were restricted to certain things‚ it mostly depended on where they’re living. Some places can respect the fact that they’re actually free‚ but they still give blacks certain rules and restrictions. There are different freedoms/restrictions blacks had to follow. Overall blacks weren’t fully free because they were not suppose to do certain things with whites or be involved in things with them. There

One of the most important facets of the philosophical study of free will is the idea of responsibility. When‚ if ever‚ is an agent responsible for their actions? While there are countless theories and schools of thought that attempt to shed light on this topic‚ several of which will be discussed here‚ there is one in particular that has stood out in our course of study thus far. It is the theory of the “Deep Self” and “Sane Deep Self” proposed by Susan Wolf. Of particular interest is this notion

Investigating the effect of changing substrate concentration on the activity of the enzyme catalase The aim of this experiment is to examine how the concentration of a substrate (hydrogen peroxide) affects the rate of reaction of an enzyme catalyse (found in liver cells) Research Question: how does changing the concentration of the substrate affect the rate of reaction of the enzyme catalyse? Hypothesis: As the concentration of the substrate increases‚ so does the rate of reaction until the reaction

The effect of time on enzyme reaction. Abstract: In this lab investigation we will observe how the amount of hydrogen peroxide is affected by catalase over time. The enzyme was added to 10 mL’s of hydrogen peroxide and observed over time to determine the relation between time and enzyme activity. The hypothesis stated that as time increased substrate would decrease. Therefore I predicted that at 60 seconds‚ there would be the least amount of H2O2. The enzyme activity mirrored my predictions

Investigate Concentration of Substrate on Catalase enzyme 1. Aim/Prediction. Aim of this experiment is to investigate concentration of substrate on catalase enzyme‚ as well to see how they work in different concentrations of hydrogen peroxide (H2O2). Prediction would be‚ that the filter paper discs that were used‚ will rise up to the surface in a time in the tube of different concentration of hydrogen peroxide. And in different concentrations the time will be different. As higher the concentration

Response to Literature Essay In the poem “Street Corner Flight‚” Norma Landa Flores explores the nature of hopefulness in the lives of two young boys living in an impoverished neighborhood. The poem begins with a sad ton‚ focusing on the hardships the young boys face. They are trapped by the difficulties that accompany poverty. By the end of the poem‚ however‚ Flores’ tone becomes hopeful that the boys might have a different future‚ a freer future. Flores’ hopeful tone reveals her message that
