Investigation on Effects of Different pH on Enzyme Activity How does the different pH buffers affect activity of potato enzyme/extract? Introduction: Proteins are polymers that are made up of smaller units/monomers called amino acids. There are 20 different types of amino acids‚ thus make up many different combinations in types‚ numbers of amino acids as well as their orders – an explanantion for why there are so many proteins. Every protein‚ due to various reactions of amino acids to each

THE EFFECT OF INCREASING THE CONCENTRATION OF DETTOL ANTISEPTIC LIQUID ON THE GROWTH OF E.COLI Background: Escherichia coli are rod shaped‚ gram negative bacteria often found in the gut of humans and other warm-blooded mammals (Jacques & Ngo‚ 2004). It is transmitted primarily through faecal contaminated food and water. Most strains of E. coli are not harmful to humans‚ however some strains are pathogenic and can cause symptoms including diarrhoea (Unknown‚ 2012). The active ingredient in Dettol

EXPERIMENT TO SHOW THE EFFECT OF DIFFERENT CONCENTRATION OF GLUCOSE ON POTATO STRIPS INTRODUCTION: Molecules of liquid and gas are constantly in motion‚ they move randomly in all directions and bounce around in all directions and bounce around and into each other. As they move‚ they tend to spread out moving from areas with many molecules to areas with fewer molecules . This process of spreading out is called Diffusion‚ for example smell of cooking travelling around the house from the kitchen

saltwater. Both can drown you but in completely difference ways. Drowning in saltwater is not as dangerous as it counterpart due to how easily you can recover from it. When you breathe in saltwater it goes in the lungs and sits there. Because the salt concentration of saltwater is really high compared to the cells in the lungs the water does not pass through and into the cells. The water is hypertonic so for the body to reach equilibrium with saltwater‚ water from the blood cells are sent out into the

“The Effect of Level of Activity on Clothespin Squeezing Amount Question: Does exercising/ resting affect the number of times you can squeeze a clothespin in a minute? Hypothesis: If the person DOES NOT exercise before the task then‚ they will be able to squeeze the clothespin more because not exercising/resting allows the body to relax and there are no buildups of waste products. Biological Explanation: Both the respiratory system and the circulatory system are involved within my experiment

EFFECT OF CHANGES IN TEMPERATURE AND SDS CONCENTRATION ON THE STRUCTURE OF BEETROOT CELL MEMBRANES. Introduction Cellular Membranes or cell membranes are biological membranes that separate the interior of a cell from the outside environment. Cell membranes are selectively permeable to ions and some molecules and control the movement of substances in and out of the cell. (Danyk‚ 2013/14) Cell membranes separate and organize chemicals and reactions within cells by allowing selective passage
