What are the end products of carbohydrate digestion? What are the enzymes involved; where are they ...

The end products of carbohydrates are monohydrates.

In the salivary glands you have salivary amylase, which acts on the starch in food and breaks it down to maltose.

Pancreatic Amylase and Maltase

As the combination of gastric juices and partially digested food enters the small intestine, the pancreas secretes pancreatic juices, which contain the enzyme pancreatic amylase. This enzyme acts on the remaining polysaccharides and breaks them into disaccharide units of maltose. In the final step of complex carbohydrate digestion, the enzyme maltase present in the lining of the small intestine breaks maltose into two units of glucose. Glucose is then absorbed and enters the bloodstream.

Sucrase and Lactase

Two additional enzymes present in the small intestine digest other disaccharides in foods. The enzyme sucrase digests sucrose or table sugar into its constituent units of glucose and fructose, while lactase breaks lactose or milk sugar into glucose and galactose. These monosaccharides are absorbed in the small intestine and transported to the liver through blood. As the human body can only utilize glucose as a source of energy, the liver converts fructose and galactose into glucose. Glucose either becomes a source of immediate energy or is stored in the liver and muscles in the form of glycogen.
