Kathleen Kramas Cells and Heredity Lab Tuesday 2:00-4:50 22 OCTOBER 2012 Membrane Permeability Decreases as Molecular Size Increases Introduction: Red blood cells are vital to organisms functioning properly. They are microscopic cells that carry oxygen from the lungs to all the tissues throughout the body. Upon transporting oxygen‚ red blood cells also exports waste‚ such as carbon dioxide‚ to the lungs where it can be expelled. Red blood cells are made up of hemoglobin which is surrounded by a

Most people if not all have indulged themselves to the modern use of technologies. From big telephones to hi-tech touch screened mobile phones‚ from typewriters to netbooks and from filmed cameras to digital cameras with the use of microsd. There were a lot of changes made to cope up with the changing environment. But for those mentioned gadgets comes their tough

Introduction In this lab‚ we experimented the effects of pH on the function of the enzyme catalase. Catalase is an enzyme that brings about the reaction by which hydrogen peroxide is decomposed to water and oxygen (Encyclopedia Britannica). The chemical reaction is shown as 2H2O2 = 2H2O + O2 (Keilin and Hartree 397). The reaction involves primarily the adsorption of hydrogen peroxide at the catalase surface. The decomposition of hydrogen peroxide by catalase is regarded as involving

Electronic balance Timer Ruler Clean everything Calculate mass of chicken liver needed for 1ml‚ 5ml‚ 10ml‚ 15ml‚ and 20ml catalyzes concentration mass to volume concentrations. In other words: 1% = . So‚ 15ml and H2O x = 0.15 g liver. This means 0.15g of liver for each percent of catalyze concentration. Overall I need 2.25g of chicken liver because I will conduct each percent with 3 trials. Measure 0.15g of chicken liver for 1% catalyzes concentration using electronic balance and

Laboratory‚ BIO124L 1/29/15 Abstract The objective in this lab was to determine the effects different conditions had on the enzyme cellobiase. We examined reaction rates in the presence or absence of an enzyme‚ the effects temperature and pH changes on the enzyme and the effects enzyme concentration and substrate concentration had on the enzyme. As expected results showed us that cellobiase works optimally when conditions are favorable. We see this when we have high substrate concentration‚ high enzyme

Introduction The aims of the lab session was to familiarize with the principles‚ operation and application of a light spectrophotometer. This report discusses an experiment to study the relationship of absorbance and concentration‚ the interaction of electromagnetic radiant energy(ERE) and matter which is an important aspect of the Beer-Lambert ’s Law. This law states that the absorption of a compound is directly proportional to the concentration of that particular compound. This is because (a & b) are
