Concentration on Enzyme Activity Rate Abstract The reaction rate of an enzyme can be affected by many factors‚ and the purpose of this experiment was to find out how an increasing substrate concentration influences the rate of an enzyme activity; we obtained data from recording the absorbance of the samples which contain the same amount of potato juice (enzyme oxidase) and different amount of catechol (substrate) while holding pH and temperature constant. Our findings illustrate that the rate of enzyme activity

do you jungle your sports‚ your social life‚ school‚ social media‚ your homework………………. and a baby. These are the issues teenage parents are facing. Not only is this hurting younger kids but also detrimental to the schools as well. School dropout rates are higher than before.

Dividend Discount Model requires input of next year’s expected dividend distributed‚ a required rate of return by shareholders and an estimation of growth rate. Since JetBlue does not pay out dividend before listed (despite dividend distributed to preferred shares shareholders)‚ such model is considered as inapplicable.

Since the 1900’s‚ the overall death rate of the population in Britain has decreased. For males‚ the death rate has dropped from 25829 in 1901 to a mere 8477 in 2000. The rate fell from 21705 to 5679 within the same period of time for females. It was noted that death rates increased during flu epidemics as well as in cold and hot weather. For example‚ about 200 000 people died in the year 1918 due to the influenza epidemic. Nowadays‚ more people die after the age of 65 while in the early 1900’s‚ only

Aim: The rate at which a reaction occurs‚ or takes place‚ is affected by various factors‚ such as the temperature at which the experiment is conducted in‚ the pressure which is given‚ the surface area which is exposed‚ use of catalysts‚ and the concentration. In this investigation‚ I would be investigating the affect of surface area‚ or particle size‚ in the rate at which a reaction occurs. Background Information: The more finely divided the solid is‚ the faster the reaction happens. A powdered

Property crime reduces investment‚ because individuals resist investment‚ if criminals reap the returns. The time of criminals‚ which could otherwise be spent productively‚ is also a social loss. These significant social costs imply that research on crime is among the most important areas in economics. Furthermore‚ as economics addresses issues beyond its conventional topics‚ work on economics and crime has indeed been among the most productive areas for research. Over the past 30 years since
