Where does the digestion of starch start in the human body?a)Stomachb)...
Mouth
Digestion of starch begins in the mouth. When we chew our food, our salivary glands release an enzyme called amylase. Amylase is responsible for breaking down starch molecules into smaller sugars like maltose. This initial breakdown of starch into simpler sugars sets the stage for further digestion in the digestive tract.
Stomach
Once the chewed food mixed with saliva reaches the stomach, the acidic environment of the stomach stops the action of amylase. Starch digestion does not continue in the stomach due to the low pH that denatures the amylase enzyme.
Small Intestine
In the small intestine, the pancreas releases more amylase to further break down the remaining starch into maltose and other simple sugars. The lining of the small intestine also produces enzymes that continue the breakdown of starch into individual glucose molecules, which can then be absorbed into the bloodstream for energy.
Large Intestine
By the time food reaches the large intestine, most of the starch has been broken down into simple sugars. The large intestine's main role is to absorb water and electrolytes from the remaining food particles, but starch digestion is mostly completed in the small intestine.
