A protein sample has been treated differently before being loaded onto the gel for SDS-PAGE. The first aliquot of the sample is treated with SDS. The second aliquot of the sample is treated with SDS and a reducing agent. If there is no difference in the number of bands when comparing the results of the two experiments, the results most likely indicate...

1. an enzyme is considered a(n) because it speeds up a chemical reaction without being used up.2. in a catalyzed reaction, a reactant is often called a(n) . an enzyme is specific because the shape of its matches only particular reactants.4. an enzyme speeds up reactions by lowering the . the between an active site and its substrate often strains bonds and the reaction proceed.6. a( , which is often a vitamin, binds to an enzyme and plays a role in catalysis.7. high temperatures or changes in ph can an enzyme, causing it to lose its shape and biological activity.
