Abstract: Enzymes‚ molecules that speed up chemical reactions‚ are specific to one substrate. In this experiment the substrate hydrogen peroxide and the enzyme catalase will be used. The higher the concentration of potato extract‚ or catalase‚ the faster the reaction and the more substrate present will result in a decrease in the time of the reaction. The amount of concentrations of enzymes and substrates are changed to determine if the reaction is further catalyzed by a greater concentration of

ADVERSE EFFECTS OF PEOPLE ACTIVITIES The Greenhouse Effect Too much carbon dioxide and other gases emitted by factories are accumulating in the atmosphere. These gases allow sunlight to penetrate the earth’s atmosphere but unfortunately‚ they also trap radiant heat and revert its escape into outer space. The immediate consequence is Global Warming‚ which is better known as the Green House Effect The rise in the average temperature of the earth could have serious consequence. Among them is

Experiment 4 – Effect of Temperature on Enzyme Activity Aim To study the effects of temperature on the activity of amylase enzyme on starch solution. Introduction Enzymes are widely known as biological catalyst. Almost all cellular reactions are controlled and guarded by enzymes. Virtually every metabolic reaction which takes place within a living organisms are catalyzed by enzymes. Enzymes are complex three-dimensional globular proteins. Some of the enzymes are built up off proteins and

The data from the experiment demonstrates that the catalase enzyme breaks down the hydrogen peroxide due to its harmful toxicity to the liver. In section A‚ the effect surface area has on the enzyme was tested. The results have proven that as the surface area increases‚ the reaction rate of the enzyme also increases. To illustrate‚ when the liver was ground‚ the bubbles from the reaction reached a maximum height of 150mm in five seconds less than the unground liver which merely reached a maximum

Temperature (⁰C) of the catalase and H2O2 Both of the solutions will be poured into test tubes/beakers and then cooled and heated to certain temperatures (10‚ 22‚ 30‚ 37‚ 45‚ and 60⁰C) and with the use of ice and a water bath ( in a separate beaker) I attempted to control the temperature of the catalase mixture as well as the H2O2 solution Dependent Variable: Rate of reaction (cm3/second) The gas syringe (± 0.5) is used to measure the amount of oxygen produced from the catalase reaction.

The Psychological Effect of Popular Media on the Increase of Crime Over time‚ it has been observed that people have a tendency to learn from the world around them and from the people they interact. The phenomenon of learning within a social context by observation can be termed as social learning. Most individuals tend to observe and replicate the behavior of things with which they come in frequent contact and this is more likely to occur if their feel an emotional attachment with the object

Effect of physical training on the capacity to secrete epinephrine M. Kjaer and H. Galbo +Author Affiliations 1. Department of Medical Physiology B‚ Panum Institute‚ University of Copenhagen‚ Denmark. Abstract Epinephrine responses to hypoglycemia and to identical relative work loads have been shown to be higher in endurance-trained athletes than in untrained subjects. To test the hypothesis that training increases the adrenal medullary secretory capacity‚ we studied the effects of

In this lab‚ we were able to determine measuring the pH of liquids work. We were able to compare the liquids based on their pH level and determine which liquid was acidic or basic. Our results showed that if something came out to be seven or less‚ according to the pH scale‚ it means that an acid is a substance that donates hydrogen ions. Because of this‚ when an acid is dissolved in water‚ the balance between hydrogen ions and hydroxide ions is shifted. Now there are more hydrogen ions than hydroxide
