Question

I am going to eat a starch rich food. What organs or necessary structures are capable of mechanically and chemically digesting the food?

What enzymes will be necessary to digest this material? Where are they produced and secreted?

What organs or structures can absorb starch? Explain your answer. If no organs are able to absorb starch, what would you do to help absorb this nutrient?

Answer 1

In the mouth, the teeth, and tongue begin mechanical digestion and the salivary glands begin chemical digestion. Once the food products enter the small intestine, the gallbladder, liver, and pancreas release secretions such as bile and enzymes that are essential for digestion to occur

Carbohydrase enzymes break down starch into sugars. The saliva in your mouth contains amylase, which is another starch digesting enzyme. Amylase is produced in saliva as salivary amylase which digests 30% of starch whereas other in the pancreas as pancreatic amylase which digests the rest

starch cannot be directly absorbed firstly the starch gets digested and the final breakdown of starches produces glucose and maltose molecules that absorb into the blood.
