Design Experiment: Enzyme Inhibitors. Research question: What is the effect of adding lead nitrate solution on the activity of amylase enzyme? Aim: To test the effect of adding nitrate solution on the activity of amylase. Background Information: Inhibitors are molecules which repress or prevent another molecule from engaging in a reaction. They are substances that attach themselves onto an enzyme and reduce or prevent the enzyme’s ability to catalyse reactions. Competitive Inhibitors are inhibitors

these differential equations follow: so an increase in prey population later shows as an increase in predators and vice versa. But this is a general model and more insight into prey predator dynamics have been observed like an article by Helen.J.Edwards and co authors who studied prey population dynamics for these type of interactions:1)Prey may compete for resources in a single habitat‚ or may be segregated‚ thus competing only indirectly . 2)Models in which a single prey species moves between

Aim: The aim of the experiment that was carried out was to see‚ at what temperature and in which standard solution‚ does the amount of dye left in the boiling tube had the highest percentage transmission. Beetroot was used for the experiment because it was easier to see the dye after the practical was completed. Putting beetroot cylinders into different boiling tubes‚ which contained

------------------------------------------------- The Mondragon Experiment * Government * Econ By Greg MacLeod | April 4‚ 2009 | 10:28 PM The concept of the corporation reaches back to Roman times. However‚ the modern business corporation evolved radically from its ancient roots into a form with little relation to the purpose as understood by historians of law. Today‚ the typical business corporation seems to be a disjointed entity whereby shareholders seek maximum income‚ labor unions

Biology College of Science De La Salle University – Dasmariñas Dasmariñas‚ Cavite Philippines ABSTRACT This experiment was performed to learn the technique of acid-base titration and to compare the efficiency of commercially available antacids by looking at their weight of HCl and weight of antacid values. The analysis of antacid tablets was highlighted in this experiment. The efficiency of antacid tablets was determined and compared when the number of grams of HCl can be neutralized by
