A)The chemical structure of an enzyme is set up so that it will only fit with one or two substrates. Almost 2000 different enzymes have been identified and each one catalyzes a different reactions. Enzymes generally have one active site where the substrate can bind, but allosteric enzymes have two or more separate binding sites. Having too or more binding sites makes their activity quicker. Catalytic activity is also effected by the temperature, ph, and …showed first 75 words of 201 total…

Now boil the liver and try it again, you should observe nothing. This is because the high temperature denatured the protein, and made the catalase ineffective. C) From the above experiment you can infer that an enzyme is a complex structure that will change shape when exposed to too much heat. ------------------------------------------------------------------------ **Bibliography**
