(a) Mouth
(b) Intestine
(c) Stomach
(d) None of the above

Answer 1

All the food that you consume goes through your digestive system so that the body can break it down and use it. Carbohydrates take a path beginning with mouth intake and finishing with colon removal. Between the point of entry and departure, there is a lot that happens.

Complete answer:
The minute the food reaches your mouth, you start to digest carbohydrates. When it's chewed, the saliva secreted from your salivary glands moistens food.
Saliva produces an enzyme called amylase, which starts the sugars' breakdown process in the carbohydrates you consume.
Chewing and combining of the food happens as food is taken in through the mouth. Given the action of saliva from the salivary glands, there is also a chemical breakdown of carbohydrates. The activity of amylase, which is a salivary enzyme, hydrolyzes 30 percent of the starch. Lysozyme, the other protein, is an antibacterial agent that avoids infections.
Starch + Maltose salivary amylase
The important things that take place here in the oral cavity are chewing food and swallowing food. Food is broken down by the chewing action of teeth into smaller pieces. It interacts with the food particles as saliva is applied, slowly moistening and lubricating the food. This small ball, which is then swallowed, is called a bolus. The pharynx helps the bolus pass into the oesophagus, from there it passes through the peristaltic motions of the oesophagus to the stomach.

Additional information: You swallow the food from there, now that it's been chewed into smaller pieces. The carbohydrates migrate to your stomach through your oesophagus. The food at this time is known as chyme. Before it does the next step in the digestion journey, your stomach produces acid to kill bacteria in the chyme.
Then the chyme, called the duodenum, moves from the stomach into the first portion of the small intestine. This triggers the release of pancreatic amylase from the pancreas. The chyme is broken down into dextrin and maltose by this enzyme. The wall of the small intestine starts to generate lactase, sucrase, and maltase from there. These enzymes break down the sugars into monosaccharides or single sugars even further.
So, the correct answer is ‘(a) Mouth’.

Note: Anything that's leftover goes to the colon during these digestive processes. Intestinal bacteria then break it down. Many carbohydrates contain fibre and the body can not digest it. It enters the colon and with the stools, is then removed.
