Enzyme Specificity Using Beta-galactosidase and Alpha-galactosidase Introduction: In order to survive‚ organisms need reactions to occur at a certain time and place. Enzymes make these reactions happen. Enzymes are highly specific causing only one enzyme to catalyze one reaction. “Induced fit” explains why enzymes act this certain way. An enzyme will surround a certain substrate and form to it for the reaction to occur in the active site. If it doesn’t form to it‚ the reaction will not occur

The Role of Beta-Blockers in the Treatment of Chronic Heart Failure In 1988 Sir James Whyte Black was honored with a Nobel Prize for medicine for his efforts in the discovery of the beta blocker propanolol and the histamine receptor agonist cimetidine. Beta blockers were originally developed to treat angina pectoris but were discovered to also treat hypertension‚ tachycardia‚ an myocardial infarctions. The discovery of propanolol was said to be the greatest discovery since digitalis. The mechanism

These cardioinhibitory drugs either block beta-adrenoceptors on the heart (i.e.‚ beta-blockers) or L-type calcium channels (i.e.‚ calcium-channel blockers)‚ which decreases cardiac output by decreasing heart rate and contractility (inotropy). Vasodilator drugs‚ which decrease systemic vascular resistance‚ are also used to treat hypertension. Included in these drugs are alpha-adrenoceptor antagonists (alpha-blockers)‚
