Answer the question below. Then, explain why your answer is the best one. Why can't a starch molecule enter a cell right after a person eats a meal with starchy foods in it?
Because a starch molecule is too large to fit into a cell and needs to first be broken down into
smaller glucose molecules in the digestive system.
Because a starch molecule only stays in the digestive system and never leaves it to go into other
systems.
Because starch molecules first need to enter the respiratory system before they can get into
cells.

Achemist at a pharmaceutical company is measuring equilibrium constants for reactions in which drug candidate molecules bind to a protein involved in cancer. the drug molecules bind the protein in a 1: 1 ratio to form a drug-protein complex. the protein concentration in aqueous solution at 25 ˚c is 1.74 x10-6 m . drug a is introduced into the protein solution at an initial concentration of 2.00 x10-6m. drug b is introduced into a separate, identical protein solution at an initial concentration of 2.00 x10-6m. at equilibrium, the drug a-protein solution has an a-protein complex concentration of 1.00 x10-6m, and the drug b solution has a b-protein complex concentration of 1.40 x10-6m.a. calculate the kc value for the a-protein binding reaction.b. calculate the kc value for the b-protein binding reaction.c. assuming that the drug that binds more strongly will be more effective, which drug is the better choice for further research?
