Enzyme Inhibition Many drugs exert their action by inhibition of an enzyme activity in the body. If the activity of an enzyme is vital to the cell or organism‚ then inhibition may lead to death of the cell or organism. It is now possible to design new drugs which are enzyme inhibitors once a target enzyme has been identified. Types of Inhibitors A) Reversible Inhibitors: The effect of the inhibitor is instantaneous‚ and it can be removed from the enzyme by dialysis so that the enzyme activity

The activity of an Enzyme is affected by its environmental conditions and changing these factors can alter the overall rate of the reaction. Reaction rates are influenced by external factors such as pH‚ temperature and salt concentration. Different enzymes have different optimum temperatures in which they are most efficient and different pH levels which is ideal for their formation of enzyme-substrate complexes. As the temperature increases‚ there is more movement of molecules and more random collisions

How Does the Change of Mass Affect the Rate at Which an Elastic Powered Car Accelerates? Research Question: How does the change of mass affect the acceleration of the Lego Car powered by elastic? Hypothesis: it was thought that the more weight added to the body of the Lego Car would slow down the initial acceleration‚ but the car would travel a longer distance due to increased momentum‚ which might overcome kinetic friction. Rationale: Some reasons of why that it was thought

March 7 2010 Controlled Substances By definition a controlled substance is a “drug or chemical substance whose possession and use are regulated under the Controlled Substance Act.” Controlled substances can range from marijuana‚ cocaine‚ heroin‚ crystal meth‚ and even prescription drugs. They are considered illegal in the state of Illinois and if caught with them you can be convicted with severe punishment. But‚ what if they are being used for medical reasons? (Controlled Substances) According

If there were stricter gun laws would violent crimes go down? Gun laws have a direct effect on the rate of violence. I believe that violence in general would go down if guns laws were more strict. For instance‚ loose guns laws have produced mass shootings. This leads me to believe that there would be less violence with stricter gun laws . These laws would include extensive background checks on the people who buy the guns‚ longer waiting periods‚ and mental health evaluations to ensure

Variable was the heat lamp‚ and the dependent variable was the temperature of the soil‚ because the temperature varied based on whether the heat lamp was turned off or on‚ and whether there was extra water added or not. Our hypothesis was proven correct‚ because the dry soil’s temperature was hotter than the damp soil’s temperature when the heat lamp was on‚ but then it decreased when it turned off‚ while the damp soil’s temperature remained the same. This is because dry soil contains little moisture

Research Question Does the concentration of substrate (H2O2 (hydrogen peroxide)) have an effect on the activity of the enzyme (catalase)? Theory The higher the substrate concentration the more quickly product is produced (rate of reaction increases) until enzyme saturation is reached at which time more substrate has no further effect. 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

Aim It is to tell how the reaction between magnesium and hydrochloric acid will be effected if we change the concentration of hydrochloric acid. Introduction In the experiment the magnesium reacts with the hydrochloric acid to create magnesium chloride and hydrogen. The balanced formula for this is: Mg(s) + 2HCL(aq) MgCl2(aq) + H2(g) Magnesium + hydrochloric acid Magnesium Chloride + Hydrogen Magnesium will react with hydrochloric acid‚ because it is higher in the reactivity series than hydrogen
