The beginning of changing starch to sugar occurs in the stomach. a. true b. false

The answer is false.

The digestion of starch starts in the oral cavity. This process requires an enzyme called amylase, which can digestion starch to Maltose, a kind of sugar. And there is salivary glands in the oral cavity, which secretes salivary amylase. These enzymes are present in saliva, so the digestion already starts in your mouth.

More starch and Maltose will still be able to be digested as glucose later on in the digestive system, especially in the duodenum, aka the small intestine. Intestinal amylase will do the job.
