Why can’t a starch molecule enter a cell right after a person eats a meal with starchy food?


A.) 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.

B.) Because a starch molecule only stays in the digestive system and never leaves it to go into other systems.

C.) Because starch molecules first need to enter the respiratory system before they can get into cells.

Answer: a.When you eat starchy food, special proteins called enzymes (which are also polymers, by the way) break starch down into glucose, so your body can burn it for energy. This starts happening right in your mouth!

Explanation:

Starch molecule cannot enter a cell right after a person eats a meal with starchy food 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. That is option A.

Digestion of food is the process that involves mixing, movement and breakdown of the food molecules into simple absorbable smaller molecules.

The nutrient components that could be found in the food are:

  • carbohydrates (starch)
  • Proteins
  • fats and oil
  • vitamins and
  • minerals

The starch, which is a complex carbohydrate, when ingested from starchy foods, is acted upon by the salivary and pancreatic amylases.

The amylases helps to break the starch into smaller glucose molecules in the digestive system that aids in the absorption.

Therefore, starch molecules enter the cells after it has been converted to a smaller absorbable glucose molecule.
