Enzymes All enzymes are globular proteins and round in shape They have the suffix "-ase" Intracellular enzymes are found inside the cell Extracellular enzymes act outside the cell (e.g. digestive enzymes) Enzymes are catalysts → speed up chemical reactions Reduce activation energy required to start a reaction between molecules Substrates (reactants) are converted into products Reaction may not take place in absence of enzymes (each enzyme has a specific catalytic action) Enzymes catalyse

Lab 9: Analysis of Commercial Bleach Introduction Many common products are effective because they contain oxidizing agents. Some products‚ which contain oxidizing agents‚ are bleaches‚ hair coloring agents‚ scouring powders‚ and toilet bowl cleaners. The most common oxidizing agent in bleaches is sodium hypochlorite‚ NaClO (or NaOCl). Commercial bleaches are made by bubbling chlorine gas into a sodium hydroxide solution. Some of the chlorine is oxidized from the molecular form (Cl2) to the

Executive summary This experiment has been conducted to accumulate data on the growth of Escherichia coli (E. coli) and to monitor how it grows under certain conditions. It has been demonstrated that the levels of glucose and dissolved oxygen were found to affect the rate of growth of E. coli proportionally with a lack of oxygen resulting in the lowering of the pH. In this experiment the growth of E. coli was studied at constant temperature (37 0C) at which it grows ideally. Experimental results for the

Discovery Restriction enzymes were discovered 40 years ago during investigations into the phenomenon of host-specific restriction and modification of bacterial viruses. Restriction enzymes protect bacteria from infections by viruses‚ and it is generally accepted that this is their role in nature. They function as microbial immune systems. When a strain of E. coli lacking a restriction enzyme is infected with a virus‚ most virus particles can initiate a successful infection. When the same strain

Review Questions 1. What is bovine spongiform encephalopathy? Why is there concern about this disease? Bovine spongiform encephalopathy‚ more commonly known as mad cow disease‚ is a fatal neurodegenerative disease‚ which causes a spongy type of degeneration in the spinal cord and brain of infected cattle. 2. What is colic? Describe at least two different types of colic. Colic simply means a pain in the stomach. Horses can experience several different types of colic‚ ranging from relatively

How Enzymes Work In Different Environments By Sarah Smith Biology1111 October 20‚ 2011 Lab Partner: Nellie Greer ABSTRACT Peroxidase is an enzyme found in potatoes that catalyzes the breakdown of hydrogen peroxide‚ H2O2‚ into O2 gas and water. We examined the different pH environments that can affect the enzyme activity during the breakdown of H2O2. In order to do this‚ we added different levels of pH‚ low‚ medium‚ and high‚ into different test tubes with the enzyme and H2O2‚
