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.

Which explanation is true about what happens to a ray of light when it strikes a mirror? a. a light ray is transmitted toward a mirror at a certain angle. the light ray is then reflected by the mirror at an equal angle but in the opposite direction of the transmitted ray. b. an incident ray strikes a mirror at an angle with a line perpendicular to the mirror. the light ray is then reflected at an angle equal to the angle of incidence but on the opposite side of the perpendicular line. c. a reflecting ray strikes a mirror at an angle with a line perpendicular to the mirror. the light ray is then refracted at an angle equal to the angle of the reflecting ray and on the same side of the perpendicular line. d. an incident ray strikes a mirror at an angle with a line parallel to the mirror. the light ray is then transmitted at an angle equal to the angle of incidence but on the opposite side of the parallel line. you so much! : -d take the time to try and answer correctly.

Can you me with this i really appreciate it

Jose and eric were given four samples in lab. the results of their analysis are shown in the table. based on the data they collected, which sample is most likely a metal?
