Research methods: Psychology 232 Effects of amphetamine on locomotor activity‚ and increased dosages leading to sensitisation on rats Jamie Rose Morley 5/10 300159481 Thursday 2-3pm Hypothesis Stewart and Badiani (1993) show in their research that tolerance may develop to a particular effect of a drug whilst at the same time also become sensitised to another effect – could be a little more clearer here. The study also found that tolerance and sensitization can be altered when given in

1.7 Factors that affect the activity of an enzyme It is important when working with enzymes to understand basic enzymatic theory behind them when selecting conditions to measure the activity of the enzymes. The factors that are known to affect the concentration of enzymes are temperature‚ pH‚ concentration of enzyme‚ concentration of substrate‚ buffer type and concentration‚ the presence of any inhibitors and cofactors (Worthington-biochem.com). 1.7.1. Temperature With most catalysed reactions‚

the effects of temperature on the enzyme activity was that the reaction’s rate would increase as the temperature increased‚ until they go over the optimum temperature where the enzymes denature and the reaction’s rate quickly drops to zero. At 5 degree C the rate is 0.00059mole PNP/min. This then increases to 0.01031mmoles PNP/min at a temperature of 50 degree C. The rate then drops drastically to -0.00215moles PNP/min. This point is where the enzymes have been denatured and have no activity‚ shown

The Importance of Extracurricular Activities A lot of schools‚ elementary through high school levels‚ struggling government’s budget cuts due to the nation’s economic downward. Looking to save academic standards‚ administrations cut other programs such as physical education or fine arts to save money. However‚ studies show that these extracurricular activities help students stayed focused on schoolwork and academic prowess. By attempting to save funds to put towards students’ learning‚ schools have

the rate in which Amylase breaks down starch into maltose. In this reaction starch is the substrate and maltose is the product. Amylase is an enzyme‚ Enzymes‚ also called catalysts‚ are in living things and there are thousand of them. Enzymes break down food by the active site on the Enzyme forming a chemical bond with a substrate and then water attacks the substrate until it is hydrolysed (split in 2).
