10. (1 point) Which of the following is a good description of an enzyme's active site? a) Formed by amino acids that are in a continuous segment of the protein's primary sequence, the active site is where product is released. Substrate is fed to the active site from a different location called the "specificity pocket". b) Formed by amino acids that can come from different parts of the protein's primary sequence, the active site of the enzyme is the location where substrate binds and gets converted to product. c) Formed by a group of amino acids that are either positively or negatively charged, the active site has a lining of positive charges on one side and a lining of negative charges on the opposing side. This allows substrates to be electrostatically "pulled" across the active site as they are converted to products. 11.
