Investigating the effect of pH on the activity of the enzyme catalase. Introduction Hydrogen peroxide (H2O2) is a very pale blue liquid which appears colourless in a dilute solution‚ slightly more viscous than water. It is a weak acid. It has strong oxidizing properties and is therefore a powerful bleaching agent that is mostly used for bleaching paper. Catalase is a common enzyme found in all living organisms. Its functions include the conversion of Hydrogen Peroxide‚ a powerful and potentially

Respiratory DiseaseLeslie ThompsonHCS/245September 22‚ 2014Sheela AlvaradoRespiratory DiseaseThe respiratory system involves breathing and the exchange of gases. It supplies oxygen to vital cells to live and function correctly. It also helps get rid of carbon dioxide‚ which is a product of cellular waste. The respiratory system is divided into two parts the upper respiratory system includes the nose‚ sinuses‚ larynx‚ pharynx‚ and mouth. The lower respiratory system which make up the lungs includes

Respiratory Care Course At Parkland College Respiratory care is important because breathing is fundamental to live. Breathing happens automatically. While you may be just sleeping‚ talking or eating‚ you do not need to spend extra efforts to make it happen. It is just the chemistry of brain that takes place and we breathe. The need of respiratory therapists come into play because according to the reports more than 24 million people in the United States and 52 million all over the world are found

Activity 4 To solve the fracturing of the bracket we are going to change in dimensions make the bracket more compact and lighter which decrease the chance of fracture. And increasing the number of holes to 2 increases the stability of the cable and giving excess strength to the bracket. By using those dimensions below: Length: 250mm Width: 210mm Height: 125mm Thickness: 12mm Thickness of base: 10mm No. of mounting points: 4 No. of holding holes: 2 Diameter of the holes: 65mm each

The Effect Of Substrate Concentration On The Activity Of The Enzyme Catalase A Level Biology Project Aims This is an experiment to examine how the concentration of the substrate hydrogen peroxide affects the rate of reaction of the enzyme catalase. Background Information Enzymes such as Catalase are protein molecules which are found in living cells. They are used to speed up specific reactions in the cells. They are all very specific as each enzyme just performs one particular reaction. Catalase
