Sample Lab Report: Factors which Affect the Activity of the Enzyme Catalase Purpose: Must include: background information about concepts involved in the lab‚ statement of purpose of the lab identification of independent and dependent variables. A hypothesis is often not necessary or appropriate. Enzymes are proteins that speed up chemical reactions in cells. They break down molecules called substrates. Each enzyme has only one substrate that it breaks down. Enzymes are produced in

Abstract The primary focus of this lab was on microscopy and simple stains. Crystal violet and Carbol fuchsine‚ simple staining components‚ were used to stain the slide in order to see the different microbes in order to determine their cellular shape and identify unknown ones by comparing. Introduction Bacterial cells are usually colorless because cytoplasm‚ for the most part‚ is transparent. Since the bacteria are colorless‚ it is almost essential to add a stain to make the bacteria more visible

Summary- The Statistics from the University of Valencia(UV) states that bullying from a cellular device affects teenagers. The preponderance of the cases seems to tell that the abuse of cyber bullying lasts for a month or less. When bullying last more than three months it is most likely the form of using a cellular device. It is most common for students/children to get bullied their first years at school by phones and the internet. The statistics from(UV) show that girls suffer more bullying than

as well as for the prosperity of the country to conduct research on this group to measure the impact of cellular phones on education. Among young people‚ the mobile is perceived and used as an always open personal link to a broad network of friends. Through this personal network‚ young people can easily make contact from almost any place‚ at almost any time and for almost any reason. Cellular phones have given the opportunity to parents to remain in contact with their children and get rid of tensions

Introduction Chemical kinetics is the study of reaction rates. A reaction rate is the speed of the change in either reactants or products over a period of time. General kinetic rate equation is: Where [A] and [B] are the concentration of the species in the reaction. The variable k is the rate constant‚ which is a function of time and catalyst presence. The variables m and n are the order of reaction for their respective species concentration. The higher the value of the reaction order the

In this lab we are going to be observing the decomposition of piglets over a month’s time. There are theory questions that have been given to us before and after the lab. We look back at our original theory to see where we went wrong‚ and then correct it. The lab was disgusting‚ surprising‚ and very interesting. The first questioned to be answered is which piglet decomposes faster‚ a piglet that is in its natural state‚ that is burnt‚ that is buried‚ and that is buried in a wooden box? With

Abstract: The Enzyme Lab results where when the liver was frozen‚ its reaction was fast‚ and when it was hot‚ it was slow‚ and the liver that was at room temperature reacted slowly to medium. Introduction: The Enzyme Lab is to conduct investigations to determine the most favorable conditions for the most efficient enzyme activity. Variables to be used testing include temperature‚ pH values and surface area. Enzymes are proteins that speed up the rate of chemical reactions‚ which would otherwise

Every person on this planet has their own hypothesis on how all organisms are related. Some may believe that there is no correlation between any of the organisms and it has always been that way. On the other hand‚ some believe that all organisms upon this earth have changed drastically‚ and we finally reached the point that we are at today after billions of years of adaptation. Now the only way to support a hypothesis is with scientific research‚ which brings me to the point of bringing up my hypothesis

process called glycolysis. Glycolysis a series of biochemical reactions in which one glucose molecule is oxidized into two pyruvic acid molecules and a small amount of adenosine triphosphate (ATP). Generation of high energy molecules are used as cellular energy sources in aerobic and anaerobic respiration. The products formed through glycolysis usually enter into the citric acid cycle and the electron transport chain to produce more energy. Fructose enters the glycolytic pathway through the liver
