An investigation to see how much oxygen is given off when different concentrations of catalase are added with hydrogen peroxide. Aim: To see if changing the concentration of catalase (found in celery) with hydrogen peroxide affects the amount of oxygen given of. Background Information: (Hydrogen peroxide - H2O2 1/2O2+H2O) Enzymes: Hundreds of chemical reactions happen simultaneously inside living cells and it’s the job of enzymes to control and regulate the various metabolic

BSC 120 Glucose Effect on Diabetic and Non Diabetic Blood Abstract: This lab was developed to investigate blood glucose and diabetes. Diabetes is a lifelong chronic disease in which there are high levels of sugar in the blood (Diabetes). The spectrophotometer was applied to this lab to determine the absorbance of blood glucose in diabetic and non-diabetic blood samples. In order to prove this‚ tests were conducted by taking the blood samples at different times right before a meal was eaten then

Glucose is one of the key nutrients required in the body. However‚ its amount in the body has to be regulated and maintained in a very narrow range. This regulation of glucose is performed by insulin hormone. Insulin is secreted at the pancreas and hence is referred to as pancreatic endocrine hormones. Insulin is secreted by beta cells‚ which are normally located at the pancreas. When the amount of glucose in the blood increases‚ the stimulus for insulin secretion triggered. The insulin level secreted

REVIEW SHEET EXERCISE 9 Renal System Physiology NAME: LAB TIME/DATE: Simulating Glomerular Filtration The following questions refer to Activity 1: Investigating the Effect of Flow Tube Radius on Glomerular Filtration. 1. Describe the effect of increasing the afferent radius on glomerular filtration rate and glomerular pressure. As the afferent radius increases the glomerular filtration rate and glomerular pressure both increase the pressure in slow steps the filtration rate greatly

Project Estimating Techniques Project Estimating Techniques One of the most important factors to the success of a project is how well the project is estimated‚ as well as how overall costs are managed during the execution phase by the project manager. Project costs and estimates are vital to the success of any organization to remain competitive in the market. Cost estimating for organizations rely heavily on resources that can sometimes be difficult to obtain. Forecasting and utilizing

Glycolysis is the sequence of reactions that converts glucose to pyruvate with the concomitant formation of ATP. Three fates of this pyruvate produced exist. In this practical the production of pyruvate and acetaldehyde by fermentation of glucose is established. A series of test tubes was set up each containing glucose and yeast suspension in buffers at different pH values. These test tubes were incubated for an hour at 37℃. Trichloro-acetic acid solution was then added to the first 2 of the 4 test tubes
