With a wide range of interactive, engaging, and assignable activities, students are encouraged to actively learn and retain tough course concepts. Experiment one alters the amount of enzyme to prove that the more enzyme you have, the faster the reaction takes place and a greater amount of product results.
Summarize As You Go. Components of the Research Report. Stating the question One very important part of the introduction section is outlining the purpose of the experiment as concisely as possible. Every textbook comes with a day "Any Reason" guarantee. Experiment two adds ascorbic acid to lower the pH.
Environmental factors such as ionic concentration and pH have been known to alter the conformation of a protein and subsequently its active site conformation. We hypothesized that enzyme amount affects reaction rates and thus we expected that reactions with increased amounts of enzyme relative to the amount of substrate will have a greater net conversion of substrates than those reactions with a lesser ratio of enzyme to substrate.
Be sure to take careful note of any changes made during the experiment as well because this could change the overall purpose of the experiment, which the introduction section describes. Instructors, contact your Pearson representative for more information.
Either active voice we measured or passive voice it was measured can be used depending on which the professor prefers. Writing the Introduction Section. Introduction and General Rules.

Preparing the Draft for Surgery. Preparing the Cover Letter. Back all statements of fact with a reference to your textbook, laboratory manual, outside reading, or lecture notes.
This may depend on the level of the course because in beginner biology classes the professors will want explanations of more terms and techniques that are considered assumed knowledge in higher level courses. Older books may show minor flaws. Talking About Proposed Research. Never set out to prove, verify, or demonstrate the truth about something.
Nothing can be "proven" indisputably in science, and it is important to keep an open mind when interpreting the results of your experiment.
I still need to do studies on sponges, cnidarians, and nematodes: Talking about Published Research Papers.
Writing Laboratory and Other Research Reports. Writing Help for Varying Skill Levels.
The object of this experiment, however, is to get the substrate, catechol, to the product, benzoquinone, by way of the enzyme, catecholase. This sentence is an attempt to state the question that the experiment tries to answer; however, it only summarizes what the experimenters actually did rather than what the purpose of the experiment was.
Enzymes are an important part of every living organism and many studies have been performed on them to try to learn more about how they work. Rather, set out to test, document, or describe. The writer makes a serious mistake by assuming that the experiment is going to prove something about enzymes.
