Enzymatic activity of Human saliva (Salivary amylase) against Temperature Proponent: Ian Angelo P. Dela Cruz BS-Biology 1-3 Prof. McJervis S. Villaruel Professor – BIOL2015(Lab) ABSTRACT This report entitled “Enzymatic activity of Human saliva (Salivary amylase) against temperature” aims to know and observe the enzyme activity of the human saliva. The research only included the use of starch-agar as the medium to observe enzyme activity during the experiment. Five starch-agar

Environment Can Effect Enzymes Introduction: In a chemical reaction there sometimes can be a catalyst present known as an enzyme. An enzyme is a protein that speeds up a chemical reaction by lowering the amount of activation energy required to start the reaction. By lowering the activation energy‚ more of the substrate is able to participate in the reaction‚ speeding it up. Enzymes are substrate specific. The substrate is what the enzyme bonds to. That is to say that enzyme A will only react with

change in pH levels has on a particular enzyme‚ in this case amylase. Hypothesis: In this investigation I expect as the pH reaches the optimum level‚ the rate of reaction will be fastest‚ compared to other pH levels. It is also suspected that after the enzyme has reached optimum level the enzyme activity will decrease. Through further study of the optimum level of amylase I found that the enzyme usually has an optima pH of 8. It is known that the pH of an enzymes environment will affect its activity

Enzyme Activity Over Different Concentrations and Effects The goals of this experiment were to examine the effectively of enzymes on samples of different enzyme concentrations and substrate concentrations. In addition‚ the experiment tested how effective enzymes are on samples of pH levels and temperature levels. A. Effect of Enzyme Concentration Hypothesis: With half as much enzyme concentration then the reaction rate will be half as much than when the enzyme concentration is equal

Lab Report: Toothpickase and Enzymes September 19‚ 2012 Olivia DePhillips Lab Partner: Joy Morgan Meyers Signature: Introduction Enzymes are biological molecules that catalyze chemical reactions. In enzymatic reactions‚ the molecules at the beginning of the process‚ called substrates‚ are converted into different molecules‚ called products. Almost all chemical reactions in a biological cell need enzymes in order to occur at rates sufficient for life. Like all catalysts‚ enzymes work

Ensure that your name/ ID no. and sample number are recorded. The report should be written according to the sample problem provided in the handout. Question: Seeds of the F1 generation derived from a cross between two different yellow-seeded varieties of corn were collected as Sample F1. The F1 plants were selfed

Enzyme Controlled Reactions 1) Describe the relationship between substrate concentration and the initial reaction rate of an enzyme-catalyzed reaction. Is this a linear relationship? What happens to the initial reaction rate as substrate concentration increases? A) The relationship between the substrate concentration and the initial reaction of an enzyme-catalyzed reaction is very productive‚ but is dramatically affected by the pH level of the given solution. The most productive pH level is

Introduction Enzymes are catalytic proteins. The purpose of a catalyst is to speed up metabolic reactions by lowering the free energy of activation or activation energy. Activation energy is known as the amount of energy needed to push the reactants over an energy barrier‚ so that the downhill part of the reaction can begin (Campbell 151). In an enzyme catalyzed reaction‚ the enzyme binds to its substrate‚ which is the reactant an enzyme acts on. In the reactions‚ the enzymes are very specific

What is Enzyme? Enzymes are protein that acts as speed up reactions and break down molecules in our body. However‚ different enzymes only work on certain types of molecules. Enzymes can accelerate the reactions by more than one million times.(3) In our human body‚ there are a total about forty thousand types of enzymes and each catalyzes different kind of molecule.(3) The molecules that enzymes help to accelerate is called substrates‚ and when enzyme is combined together with the substrate‚ it

The Effect Of Substrate Concentration On The Activity Of The Enzyme Catalase A Level Biology Project Aims This is an experiment to examine how the concentration of the substrate hydrogen peroxide affects the rate of reaction of the enzyme catalase. Background Information Enzymes such as Catalase are protein molecules which are found in living cells. They are used to speed up specific reactions in the cells. They are all very specific as each enzyme just performs one particular reaction. Catalase
