Put these steps in the mechanism of chymotrypsin catalysis in order from first to last. note that your textbook may not break out each of these steps individually, but all steps should be ordered. (there will be eight steps.) a. his 57 catalyzes removal of h from ser 195 hydroxyl. b. his 57 donates h to n of sissile peptide bond, tetrahedral intermediate decomposes. c. the portion (n-terminal end) of the original substrate with the new carboxylate terminus diffuses away. d. water donates h to his 57. e. resulting oh attacks carbonyl of remaining substrate. f. his 57 donates h to ser 195 o, leading to collapse of thtrahedral intermediate. g. the portion (the c-terminal end) of original substrate with the new amino terminus diffuses away. h. ser 195's nucleophilic o attacks carbonyl c of substrate.

The atomic radius of sodium is 186 pm and of chlorine is 100 pm. the ionic radius for na+ is 102 pm and for clβ is 181 pm. in going from na to cl in period 3, why does the atomic radius decrease while the ionic radius increases? a. the inner electrons in the sodium cation shield its valence electrons more effectively than the inner electrons in the chloride anion do. b. the inner electrons shield the valence electrons more effectively in the chlorine atom than in the chloride anion. c. the outermost electrons in chloride experience a smaller effective nuclear charge than those in the sodium cation do. d. the outermost electrons in chloride experience a larger effective nuclear charge than those in the sodium cation do. e. monatomic ions are bigger than the atoms from which they are formed.
