Frequently Asked Questions

For students

If I order a paper sample does that mean I'm cheating?

Not at all! There is nothing wrong with learning from samples. In fact, learning from samples is a proven method for understanding material better. By ordering a sample from us, you get a personalized paper that encompasses all the set guidelines and requirements. We encourage you to use these samples as a source of inspiration!

Why am I asked to pay a deposit in advance?

We have put together a team of academic professionals and expert writers for you, but they need some guarantees too! The deposit gives them confidence that they will be paid for their work. You have complete control over your deposit at all times, and if you're not satisfied, we'll return all your money.

How should I use my paper sample?

We value the honor code and believe in academic integrity. Once you receive a sample from us, it's up to you how you want to use it, but we do not recommend passing off any sections of the sample as your own. Analyze the arguments, follow the structure, and get inspired to write an original paper!

For teachers & parents

Are you a regular online paper writing service?

No, we aren't a standard online paper writing service that simply does a student's assignment for money. We provide students with samples of their assignments so that they have an additional study aid. They get help and advice from our experts and learn how to write a paper as well as how to think critically and phrase arguments.

How can I get use of your free tools?

Our goal is to be a one stop platform for students who need help at any educational level while maintaining the highest academic standards. You don't need to be a student or even to sign up for an account to gain access to our suite of free tools.

How can I be sure that my student did not copy paste a sample ordered here?

Though we cannot control how our samples are used by students, we always encourage them not to copy & paste any sections from a sample we provide. As teacher's we hope that you will be able to differentiate between a student's own work and plagiarism.

harvard business school essay topics daoine oga essay - enzyme concentration on the initial rate of reaction. The pancreas releases several enzymes, including proteases, which could be used to investigate the effect of enzyme concentration on initial rate of reaction. Other enzymes, including catalase, could be used to investigate the effect of enzyme concentration on initial rate of reaction. Jun 07,  · In this experiment, the effect of enzyme concentration is chosen to be investigated on the rate of reaction catalysed by enzyme catalase. An increase in enzyme concentration will increase the active site available and thus increase the rate of reaction until it reaches maximum velocity when all active sites of the enzyme molecules are engaged. Oct 22,  · When catalyzing a reaction, the enzyme binds to the substrate (Bolsover et al., ). If there is a higher concentration of enzyme, this means that there will be more enzyme to bind to substrate at once, therefore making the turnover rate of substrate to product higher. This is why a higher concentration of enzyme produces a higher turnover rate. rate my essay

When looking at graph 1 it is easy to see a linear relationship between the rate of formation of NADH and the concentration of the enzyme. As enzyme concentration increases the rate of reaction increases because substrates are more likely to collide with available enzymes. Enzyme Activity 6 Laying the Foundation in Biology Enzyme Activity Measuring the Effect of Enzyme Concentration Enzymes are proteins that serve as biological catalysts in a wide variety of life sustaining chemical reactions that take place in cells. As catalysts, enzymes lower the amount of energy required to make a reaction occur.

Inhibitor was added under the above conditions at a concentration of ×10 −5 mol/L and initial reaction rate r sI was measured at different substrate concentrations. The Effect of Enzyme Concentration on the Reaction Rate J Objectives/Goals Enzymes are organic catalysts that speed up reactions by decreasing the activation energy needed to start the chemical reaction. Therefore, my hypothesis is that as the enzyme concentration increases, the speed of the chemical reaction will also increase. Hypothesis If temperature, substrate concentration, enzyme concentration and pH are factors that dictate the rate at which enzymes denature proteins, then an increase in these factors will result in an increase of the rate of these reactions.

Enzyme activity is generally greatest when substrate concentration is unlimiting. When the concentration of the product of an enzymatic reaction is plotted against time, a similar curve results, Figure 6.

personal statement essay - In such a experiment, the result of enzyme concentration is chosen to be investigated on the rate of reaction catalysed by enzyme catalase. A rise in enzyme concentration will raise the lively site available and so improve the rate of effect until it reaches maximum speed when all active sites of the enzyme molecules are involved. because the product of each reaction is removed in the subsequent reaction. In all this, the role of the enzyme appears to be simply that of a rate facilitator. But it is important to illustrate in addition, the power than an enzyme hasper se to influence the direction in which a reaction goes. Only calculations for the first enzyme concentration will be shown, the others have been calculated in the same way.

Aug 17,  · Concentration of Substrate. In the presence of a given amount of enzyme, the rate of an enzymatic reaction increases as the substrate concentration increases until a limiting rate is reached, after which further increase in the substrate concentration produces no significant change in the reaction rate (part (a) of Figure \(\PageIndex{1}\)).
