Investigating the effect of changing substrate concentration on the activity of the enzyme catalase The aim of this experiment is to examine how the concentration of a substrate (hydrogen peroxide) affects the rate of reaction of an enzyme catalyse (found in liver cells) Research Question: how does changing the concentration of the substrate affect the rate of reaction of the enzyme catalyse? Hypothesis: As the concentration of the substrate increases‚ so does the rate of reaction until the reaction

lab-Catalase experiment Aim: To investigate enzyme kinetics‚ using different concentration of the enzyme. Hypothesis: The assay system used in the lab consists of a filter paper disc coated with the enzyme and the dropped into a papercup of substrate (Hydrogen Peroxide). As the hydrogen breaks down the hydrogen peroxide into hydrogen and oxygen gas‚ the bubbles of oxygen gas collect underneath the filter and make it rise to the surface of the hydrogen peroxide. The time it takes for the filter to rise

Enzymes control the rate of metabolic reactions‚ they act as biological catalysts‚ which means they are used but not used up and they also control the speed of the reaction. Enzymes are proteins which means that anything that disrupts this structure such as high temperature or change in pH will affect the enzyme activity. There are many factors affecting enzyme action for example temperature effects them‚ if the Increasing the heat gives molecules more kinetic energy so they vibrate this can then

Increasing number of animals and plants are dying out‚ but little has been done to prevent. This problem has given rise to great public concern now. In this essay‚ I’ll analyse some possible causes of this phenomenon and then propose some solutions. Firstly‚ some people think it is waste of resource to prevent animals and plants. They suggest that the money should be better spent on human population. They want take more space and totally ignore the animals’ and the plants’. Secondly‚ human being

society‚ animals are wrongfully forced into mistreatment through various methods and should be protected with a code of rights similar to the way humans are protected by codes of rights. Abuse and other acts of cruelty cause them emotional and physical pain even if they cannot verbally express how they are feeling. A. One of the contributing factors is that in modern society people don’t think that animals are morally entitled to having rights. 1. Animal rights is a belief that animals hold an intrinsic

Cellular Biology furthers technology-Enzymes in the Dairy Industry Since ancient times‚ enzymes have played an important role in food production. Especially in the diary industry‚ some enzymes are required for the production of cheese‚ yogurt‚ and other dairy products‚ while others are used in a more specialized fashion such as improving texture or flavour of the product. Enzymes are used to catalyze the desirable reactions in industrial processes. Today‚ enzyme applications in such processing get

The Effects on Enzymes By Bailey Rose The Effects on Enzymes Bailey Rose 10/31/2011 Abstract In this lab exercise‚ the study of enzyme catalase‚ we viewed the breakdown of hydrogen peroxide into water and oxygen. The purpose was to isolate catalase from starch and measure the rate of activity under different conditions. Changes in temperature and pH along with Substrate Concentration and Enzyme Concentration were the conditions tested in the experiment. Our class performed

Abstract: Enzymes help determine a phenotype through proteins. The experiment presented tests how enzymes affect the pigment in the eye of Drosophila. What was resulted in this experiment is that when certain enzymes change‚ a mutation is created‚ causing the change of pigments in the different Drosophila’s eyes. The production of one enzyme is one gene and a mutation of this gene can cause an enzyme to be inactive which leads to the phenotype changing. Introduction: George W. Beadle and Edward L

An enzyme is a biological catalyst‚ meaning that it is a substance that possess the ability to increase or speed up the rate of reaction without itself being used up in the process. Enzymes provide an alternate reaction pathway by lowering the activation energy needed for a reaction to occur. For two molecules to react they must collide with each other‚ however‚ they have to collide with sufficient energy. Sufficient energy means that between them they have enough energy to overcome the energy barrier

wouldn’t be able to have breaks‚ Time to play and live our own lives with our own lives. Many places in the world don’t allow people to have breaks and time to play. As we have in America. This right is very important‚ for much reason. Everybody should be able to have this right in there life. The first reason is that‚ breaks are very important. Without it our bodies would be exhausted. We wouldn’t be as healthy as we would be‚ if we were given breaks. Like we a. With these breaks we have time to rest
