In this folio task‚ the impact of drug absorption and blood stream concentration‚ on the human body‚ will be observed. The rate of absorption and clearance of the drug‚ relies on many factors. The drugs blood stream concentration‚ time of administration‚ absorption rate‚ clearance rate and the effect of certain parameters‚ will be calculated. This can be completed through using a surge function‚ calculus (derivatives) and straight line graphs (). Graphing technology on the graphics calculator

investigating how the rate of reaction differs when we change the concentration of Hydrochloric Acid whilst reacting with Magnesium. The rate of reaction is explained by the Collision Theory. This theory explains how various factors affect the reaction rates and how chemical reactions occur. The 4 factors of the Collision Theory are: • Temperature • Concentration • Surface area • Catalyst I am investigating how different concentrations of acids affect the rate of reaction. However I must control

The Effect Of Enzyme Concentration On Enzyme Activity The pancreatic duct in individuals who have cystic fibrosis frequently becomes blocked‚ reducing or preventing the release of pancreatic enzymes into the small intestine. The aim of this activity is to investigate the effect of a reduction in enzyme concentration on the rate of reaction‚ in this case the breakdown of protein by protease enzymes. Aim – Milk powder contains a white protein called casein. A white suspension of

Purpose: To find the percent of sugar by mass in chewing gum Hypothesis: The percentage of chewing gum that is sugar for bubble gum is 30%‚ 20% for juicy fruit and 25% for stride gum. Mass Of Juicy Fruit Mass Of Bubble Gum Mass of Juicy Fruit unchewed | 7.12g- 1.72 = 5.4 g | 5.80g- 1.72g = 4.08 | 4.52g- 1.72g = 2.80g | chewed | 3.00g- 1.72g= 1.28g | 2.24g-1.72g =0.52g | 2.86g-1.72g= 1.14g | Percent of Sugar | 3.00g x 100/ 5.4 = 55.5%

Research has determined that ageing is important to consider when looking at neurodegenerative diseases and there cause‚ such as Alzheimer’s disease. It is thought that neuronal loss is primarily involved in neurodegeneration when in fact it seems that synaptic strength‚ or plasticity‚ is more vulnerable to the process of ageing (1). Biochemical and structural alterations of the synapse such as changes in lipid composition in certain areas of the brain are also thought to be associated with this

Concentration is graphed‚ a straight line will result. The regression line’s equation is used to determine the concentration of an unknown solution once the percent of T has been measured. The equation of Beer’s Law (A=abc) is an efficient way of

EFFECT OF CONCENTRATION ON REACTION RATE The aim of this experiment is to find the effect of varying the concentration of iodide ions on the rate of reaction between hydrogen peroxide and an acidified solution of potassium iodide: H2O2(aq) + 2H+(aq) + 2I⁻ → 2H2O(l) + I2(aq) The course of this reaction can be followed by carrying it out in the presence of small quantities of starch and sodium thiosulfate solutions. As the iodine molecules are produced they immediately react with the thiosulfate

Background Information: Enzymes such as catalase are globular protein molecules with catalytic properties. A catalyst is a substrate which can alter the rate of reaction without itself undergoing any permanent change. As they are not changed

Treblinka Concentration Camp The Holocaust was a horrifying event. Adolf Hitler rose to power in 1933. Later they started constructing places to hold the Jewish and other people they called these place concentration camps.Treblinka was one of those camps. Treblinka was a part of Hitler’s final solution. Now you will learn about this terrible camp. “In July of 1942‚ the Operation Reinhard authorities had finished a killing center‚ known as Treblinka II.” (Treblinka) From late July and September 1942
