Title: “The Effect of Substrate Concentration‚ Enzyme Concentration‚ pH and Temperature on Enzyme Activity” Abstract: In the following experiments we will measure precise amounts of potato extract as well as Phenylthiourea‚ combined with or without deionized water and in some instances change the temperature and observe and record the reaction. We will also investigate the different levels of prepared pH on varying samples of the potato extract and the Phenylthiourea and record the results.

World War II was the largest conflict in human history and in the aftermath‚ Europe was devastated. During the war‚ most of the countries in Europe had spent exorbitant amounts of money and their gold reserves were incredibly depleted. In addition to this‚ many countries had taken out large loans to pay for the war. The United States had given the grand majority of these loans and became the largest creditor after the war. Great Britain‚ on the other had‚ had been the largest creditor before the

Biology “Enzyme Activities” Introduction: Enzymes have extremely interesting properties that make them little chemical-reaction machines. The purpose of an enzyme in a cell is to allow the cell to carry out chemical reactions very quickly. These reactions allow the cell to build things or take things apart as needed. This is how a cell grows and reproduces. At the most basic level‚ a cell is really a little bag full of chemical reactions that are made possible by enzymes (Brain). Laboratory

An investigation into the effects of temperature on enzyme action An enzyme is a biological catalyst that speeds up the rate of reaction in certain biological functions. They play a vital role in many aspects of human physiology and are necessary for the functioning of a number of systems‚ for example in the digestive system to help to break down food. All enzymes have a unique active site that can fit on to a particular molecular arrangement on a target substrate; a substance e.g. carbohydrate

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

What is your opinion about using animals for research? When thinking about how much I love and adore animals‚ I also think about how far we have gotten scientifically because of their sacrifices. When reading the APA website I agree with the Justification of the Research and that Research should be undertaken with a clear scientific purpose. There should be a reasonable expectation that the research will: 1. Increase knowledge of the process underlying the evolution‚ development‚ maintenance‚ alteration

Investigating the effect of pH on amylase activity Aim The aim of the experiment is to determine the effects of different pH and the rate of reaction on fungal amylase and starch. Introduction The enzyme amylase is found in the human body‚ it catalyses the hydrolosis of internal glycosidic bonds in polysaccharides‚ the breakdown of starch into sugars. Amylase is present in human saliva‚ where it initiates the chemical process of digestion. Enzymes work best at an optimum pH of 7 which

Effects of Using Computers As the world is developing rapidly‚ people rely more and more on science and technology. When they define the concept of science and technology‚ “most people today think of silicon chips‚ iPods‚ high-definition TVs‚ and visual cell phones” (Wilson 320). Among those high-tech inventions‚ cars and cell phones are two scientific inventions that mostly affect people’s lives. For example‚ they can get to the destination faster or simply make a phone call to talk instead of

PSYC 101 – Experiment Assignment (40 pts) Students will carefully observe acts of aggression and prosocial behavior on television‚ report their observations‚ and analyze their data to draw conclusions. Watch 20 minutes of each of the three types of programs (do not code behavior in commercials). Record every aggressive act and prosocial act. Some categories will have several acts. Your chart and discussion will focus on comparing the following three types of programs you will watch: 1) children’s
