Effects of Changes in Physical Properties on Enzyme Activity By Alex Hoffmann First Individual Lab Report Wednesday 7:30-10:15pm 10/24/12 Meghan Duell Abstract The goal of this lab was to determine the effects of certain physical properties on enzyme activity. Enzyme activity was measured by the height of the bubbles that appeared after the enzyme was added which are proportional to the rate of the reaction when time is constant. The fact that enzyme activity is affected by physical

CEIC2001 – Fluid Mechanics Notes Fluid – A substance which is capable of flowing. A fluid is also a substance which has no permanent resistance to change in shape i.e. a solid can resist a shear stress‚ τ by static deflection; a fluid cannot‚ any shear stress applied to a fluid will result in the motion of that fluid for as long as the shear stress is applied. τ=FA Where F = force which is tangent to a surface (shear force)‚ A = area of moving plate in which shear force is applied to.

WHAT IS FLUID MECHANICS ? FLUIED: Any thing whose particles can move easily from one place to another that means shape can be easily changed upon the application of negligible force. MECHANICS: Study of response of bodies upon the application of force. FLUID MECHANICS : Fluid mechanics may be defined as the branch of engineering science which deal with behavior of fluids under the condition of rest and

Analysis Paper: Fluid Volume Deficit “Fluid volume is a term that describes the balancing of input and output of fluid in the body” (Welch 2010). This balance can be affected by many factors: inadequate intake‚ shock‚ vomiting‚ diarrhea‚ or too much output. It can also be caused by third spacing. Fluid volume balance is very important to monitor patients because it can affect every body system and can easily be altered. Fluid volume deficit is more commonly referred to as dehydration.

For Acidic hydrolysis‚ SAC was found to be well susceptible to acid hydrolysis with 0.05 M HCl at 40 ˚C for 30 min caused about 8% reduction in the peak area of SAC (Fig.4a). While this mild condition didn’t affect VAL. While‚ nearly 27% was the reduction in SAC’s peak area when subjected to alkaline hydrolysis. This considerable decline in the peak area of SAC when subjected to 0.01 M NaOH at 40°C for 30 min revealed degradation products peaks appeared at 3.339 and 9.482 minutes (Fig.4b) and they

Hypothesis The optimum temperatures of Alcalase and Savinase will be different. Above and below their optimum temperatures activity will decrease. Biological explanation This investigation is designed to look at the effect of temperature on the activity of the proteases Alcalase and Savinase. By the end of it I hope to know the optimum temperature of both proteases. The substrate I am going to use during the experiments is the protein gelatin‚ which is a translucent‚ colourless‚ brittle solid

Effects of Human Activities on the Lake Ecosystem I. Introduction On the first exercise of the Environmental Biology class‚ the students have learned what an ecosystem is and what its significance to the survival of the living and non-living are through analysis of forest and agro-ecosystems. The ecosystem as the basic unit for ecological study (Evans‚ 1956) consists of the complex of interacting organisms inhabiting a region with all the non-living physical factors that make up their environment

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

little read: ... The cell membrane structure-Fluid mosaic model The cell membrane separates a watery cytoplasm from a watery external environment also known as ECF. The phospholipids are arranged in a double layer (lipid layer) with the hydrophilic heads facing outward (cytoplasm or ECF) and the hydrophilic tails turned in towards each other. The unsaturated fatty acids are not bonded to each other and form a fluid. Fluid Mosaic model. The term "fluid" is used because the phospholipid molecules and

to learn... when is it that we will understand that the well-being of the environment and our survival are intricately woven into each other. Good morning respected teachers and my dear friends ...today I Nikita am going to speak about how human activities are affecting flora and fauna? We are facing a serious crisis in biodiversity‚ the variety of animals‚ plants and their habitats. We humans are part of this biological diversity and depend on it in many ways. The rate that animal and plant species
