    undergoing a permanent change themselves. These proteins are able to do this by lowering the activation energy of a reaction. To add on‚ enzymes require specific conditions under which they can work best. Reactions occur at faster rates when the temperature is higher. However‚ the rate of an enzyme-catalyzed reaction is reduced or can be stopped if the temperature becomes too high. This is due to the fact that enzymes become denatured at high temperatures. Denaturation occurs when the shape of an enzyme is

    Each of these trials was repeated three times to ensure proper accuracy. After concluding the reactions they were placed into a spectrophotometer (A580) for analysis. Graphing the values of the absorbance to time for each pH it was found that the rate of reactions in the neutral pH solutions were much higher than that of the acidic solution. We concluded that this was because of the possibility of an enzyme to become denatured in acidic solution. Introduction The study of enzymes is crucial

    infarction based on pathology: Transmural: associated with atherosclerosis involving a major coronary artery. It can be subclassified into anterior‚ posterior‚ inferior‚ lateral or septal. Transmural infarcts extend through the whole thickness of the heart muscle and are usually a result of complete occlusion of the area’s blood supply.[13] In addition‚ on ECG‚ ST elevation and Q waves are seen. Subendocardial: involving a small area in the subendocardial wall of the left ventricle‚ ventricular septum
