    May 1‚ 2013 Enzymes as Drug Targets Enzymes are defined as any of numerous proteins produced in living cells that accelerate or catalyze the metabolic processes of an organism. Enzymes are usually very selective in the molecules that they act upon‚ called substrates‚ often reacting with only a single substrate. The substrate binds to the enzyme at a location called the active site just before the reaction catalyzed by the enzyme takes place. Enzymes can speed up chemical reactions by up to

    Conclusion 7 8.0 Appendix 8 9.0 Reference List 10 1.0 Abstract Enzymes are catalysts to ensure homeostasis in the body [2]. Homeostasis is the tendency to maintain the internal environment [2]. Hydrogen peroxide is an oxidizing agent that can be decomposed by catalase [11]‚ the liver is able to decompose hydrogen peroxide enzymatically because it contains catalase [12]. The reaction rate of an enzyme catalysed reaction under the effect of changes in temperature was tested in this

    Those colonies were subjected to a Gram-stain to ensure that P. larvae‚ a Gram-positive bacterium was isolated (Figure 7). However‚ there was a presence of other bacteria visible on the Gram-stain. Therefore‚ the catalase negative colonies were streaked onto MYPGP agar to further isolate P. larvae. The pale colonies that grew on those plates were subjected to a 3% potassium hydroxide test. No signs of cell lysis was present; therefore‚ P. larvae was isolated. Isolating

    Photosynthesis is a process that allows organisms to trap sunlight energy and convert it directly into potential chemical energy. Enzymes are required in order for the biochemical reactions to occur because they act as a catalyst to convert energy from sunlight into chemical potential energy. Two consecutive steps allow the photosynthesis process to take place. These steps are light-independent reactions‚ and light dependent reactions. The occurrences of Light-independent reactions happen in the
