Put these steps in the mechanism of chymotrypsin catalysis in order from first to last. Note that some references 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.

water   molecules stay close to each other through cohesion, the collective action of hydrogen bonds between water molecules. cohesion plants draw water upwards from the root through the stem's transport tubes (xylem) to the leaf. this transport occurs even in large trees and against gravity. transpiration, evaporation of water from plant leaves, creates a tension on water molecules being pulled up from the stem and roots.

water also has high (the attraction of one substance to another) properties because of its polar nature. adhesion of water molecules to plant cell walls counteract gravity while water is transported from roots to leaves.

water exhibits a very high surface tension when compared to other liquids. surface tension is a property of a liquid that holds the surface together and allows it to resist an external force. by capillary action, the water forms concave menisci inside the pores. the high surface tension of water pulls the concavity outwards, generating enough force to lift water from the roots to the leaves of plants.

thus, cohesion, along with adhesion and surface tension creates a capillary action that keeps water molecules interacting and moving through the plants out to the leaf cells.

therefore, option d) is the correct answer.
