Temperature affecting enzyme activity Aim: To see how temperature can affect enzyme activity Prediction:-I think the one that will work best will be the rennin placed in milk at 37oC My independent variable will be the temperature My dependant variable will be how thick the milk becomes The equipment I need is milk‚ 5 test tubes‚ rennin‚ water bath‚ boiled rennin‚ a glass rod and a stopwatch Introduction: Rennin is an enzyme found in the stomach‚ its function is to solidify milk. We

Enzymes are catalytic proteins which speed up the rate of reactions. Every enzyme has a specific function – meaning‚ they can only bind to certain substrates. Because these enzymes are proteins‚ they can be denatured. Enzymes can be denatured by many factors‚ such as pH and temperature. This lab was divided into three parts which examined the effects of pH‚ enzyme concentration and temperature on the rate of which enzymes catalyze. The pH is an index of hydrogen ions. In acidic conditions‚ where

TITLE: Enzymes AIM: To investigate the effect of temperature on the enzyme lipase INTRODUCTION: The phenomenon of catalysis makes possible biochemical reactions necessary for all life processes. Catalysis is defined as the acceleration of a chemical reaction by some substance which itself undergoes no permanent chemical change. The catalysts of biochemical reactions are enzymes and are responsible for bringing about almost all of the chemical reactions in living organisms. Without enzymes‚ these

WRITING A SCIENTIFIC RESEARCH ARTICLE FORMAT FOR THE PAPER Scientific research articles provide a method for scientists to communicate with other scientists about the results of their research. A standard format is used for these articles‚ in which the author presents the research in an orderly‚ logical manner. This doesn ’t necessarily reflect the order in which you did or thought about the work. This format is: TITLE 1. Make your title specific enough to describe the contents of the paper‚ but

The scientific method is usually presented in science textbooks to show a simpler way to perform scientific investigations. Although the process of science is never predetermined‚ the scientific method may help create a prediction as to what is going to happen. The scientific representation in a similar way is using the evidence found within the experiments; however‚ this unfortunately does not tell you or show you how the science actually works. The Scientific Method isbroken down into 5 simple

1.03 Scientific Method PART 1 1. The experiment isn’t adequate because there are multiple factors when there can only be one independent variable. 2. If Tyrone and Valerie both fly differently designed paper airplanes then Tyrone’s will fly farther because it has longer wings in comparison to Valerie’s wings. a. independent variable: length of wings b. dependent variables: type of paper‚ wind (if any)‚ shape of plane‚ width of the actual plane

considering this project. Our teachers named Ralph Lim‚ Neboy Navarez and Dinnes Salaga for giving us their honest comments during our final defense. We really appreciate their presence because without them‚ we would not be able to improve our research paper. Last but not the least‚ is our loving and forgiving heavenly Father for giving us knowledge‚ wisdom and a lot of things we need to make for the completion of this research possible. Introduction Most students nowadays prefer to do things in

8/12/2013 Intro I am going to investigate a factor that affects the rate of enzyme activity What are enzymes and how do they work? Enzymes are biological catalysts - catalysts are substances that increase the rate of chemical reactions without being used up. Enzymes are also proteins and thus have a specific shape. They are therefore specific in the reactions that they catalyse - one enzyme will react with molecules of one substrate. The site of the reaction occurs in an area on

up with theory was Alfred Wegener. Wegener had a PhD in astronomy but always had an interest in geoscience. “Wegener was browsing in the university library when he came across a scientific paper that listed fossils of identical plants and animals found on opposite sides of the Atlantic” (UCMP‚ Alfred Wegener). This paper sparked quite an interest for Wegener‚ and he began to research this topic extensively. He knew to prove this “crazy” theory he would have
