Opening Speech for a Sports Event Ladies and Gentlemen Boys and Girls It gives me great pleasure to be at the Opening Ceremony of the 19th Annual Sports Meet. I would like to take this opportunity to extend a warm welcome to all participants and physical education teachers. It is the strong commitment to track and field‚ and to the development of our youth‚ is the reason why we have all gathered here . This event speaks for the commitment that all of us in the school hold for the sport

Enzyme kinetics (catalase/kmno4) Enzyme catalysis Farah Mohamed galal 22-3014 t09 Introduction: E + S → ES → E + P Enzymes are proteins which act as a catalyst in biochemical reactions(affect the rate of achemical reaction). The substrate binds to the active site of the enzyme. Any deformation of the active site will affect the activity of the enzyme‚ these are some ways that enzyme action may be affected because of them: 1- Salt concentration: If it is close to zero or very high

degeneration of muscles is causes by progressive damage and loss of muscle cells with linked to weakness. There is a decrease in the force which muscle can exert. Our muscle become tired and it will cause of muscle fatigue. There are common causes why our muscles become weak. Lack of use is the most common causes of muscle weakness. Muscles become chunky and more floppy because muscles are not used then the fibers within the muscles partially replaced with fat. Aging is another factor of muscle degeneration

Enzyme Catalase Activity in Reaction with the Substrate Hydrogen Peroxide Abstract We performed these experiments to observe the effects of enzymes on the rate of reactions. We tested and compared the activity of the enzyme catalase on the substrate H2O2 in various states and percentages‚ and observed the absorption values of the enzyme-substrate relationship at different concentrations. Our results show that the more substrate available‚ the quicker the reaction will happen except in one test

Muscles are responsible for all conscious and unconscious movement. It is how we move and react to an environment. There are three types of muscles in the body include the skeletal muscle‚ smooth muscle‚ and the cardiac muscle. Whether you are running‚ walking‚ breathing‚ eating‚ sleeping‚ or typing it all involves some sort of muscle action. Muscle cells that shape‚ form‚ and outline the whole human skeleton is called a muscle fibers. There are two types of muscle fibers: Type I (slow-twitching

protease which conducts hydrolysis forming peptides. It is an enzyme which is secreted by the pancreas into the small intestine and works best in an alkaline environment. Egg white is used in this practical as it is found to contain the protein/ enzyme trypsin. pH is the measure of the amount of H+ ions in a solution‚ these ions affect the shape of the enzyme. Hypothesis: That as pH increases‚ the rate of enzymatic activity increases until the optimum pH is reached. Aim: To investigate the

If exercise maintains our health‚ do you maintain exercise? Some people may spend their little time or get up early to do exercise. But some people may think that it is not necessarily for them. The main point is that can exercise really advance for our healthy body? The answer is yes. And I don’t agree exercise can be detrimental to health. Exercise is the best way to regulate our weight. We burn our calories thought doing exercise‚ specially doing the aerobic exercise‚ which burning calories

Most people do not know about athletic trainers and their jobs. Therefore‚“They are the unsung hero’s of sports medicine”‚ says writer Vincent O’Brien. Their not credited enough for the challenging labor they undertake. To understand more about athletic trainers‚ a person needs to know about the careers available‚ the jobs they do‚ and the benefits they provide‚ so that they can acknowledge the importance of athletic trainers in the field of medicine. Athletic trainers have a vast variety
