2. Enzymes are important biological molecules and they act as catalysts for specific chemical reactions. Their biological function is determined by their 3 dimensional shape and the functional groups present in the active site. (a) What are the main mechanisms by which an enzyme increase the rate of a reaction? (b) What is a cofactor in an enzyme mediated reaction? (c) Give the name of a cofactor (structure if possible) and indicate the type of reaction that it facilitates. 3....

Topic: Lactase persistence, enzymes, and genetic expression We started this term looking at the persistence of the enzyme lactase, which breaks down a specific sugar in milk. Lactase persistence shows interesting global distribution patterns due to evolution and natural selection. The lactase enzyme acts like many other biological catalysts. Write an essay about lactase persistence and the function and expression of the lactase enzyme. Make sure to address: Define evolution and the selection pressure that lead to diversity in lactase...

ch 14 answer each of these.
answer all 3 please
HI HCI reactants Reaction intermediates are species that are formed in one step of a mechanism and consumed in another step. For example, can act as an intermediate in the following reaction: H2(g) + 2Cl(g) + 2HCl(g) + 12(g). You can often express the concentration of in terms of the concentrations of the of the overall reaction to be consistent with the experimentally observed rate law as the overall reaction...
