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.
