In the physiological pH range, the nitrogen in the imidazole ring can be easily protonated/deprotonated. This allows the histidine side chain to—     function as either a general acid catalyst or a general base catalyst.     act as a strong reducing agent.     interact with the guanidino group.     either gain or lose a single electron.     bind either H+ or OH-.

Write a sample chemical reaction of chymotrypsin in a complete balanced equation  label the following properly: substrate/s, cosubstrate/s, and cofactor/s Show all the changes in the reacting components small molecules should be in their skeletal form large molecules could be shown as hybrid structures - reacting/interacting groups in skeletal form, the rest of the molecule as abbreviations/blocks/shapes

Catalysis through proximity and orientation effects involves: (select all that applies) Group of answer choices binding of acidic and/or basic groups in the binding site facilitating chemical reactions by binding substrates close to specific groups binding of substrate in specific, restrictive orientations depending on metal ions for catalysis

Modify the structure to show the MAJOR product that would be formed in the following reaction. HNO3, H2SO4
