Question

What process involves digestion by pancreatic amylase, conversion of starch to disaccharides, and subsequent absorption of glucose, fructose, and galactose into the bloodstream and liver?

a) Glycolysis
b) Glycogenesis
c) Gluconeogenesis
d) Carbohydrate digestion

Answer 1

The correct answer to the described process is carbohydrate digestion, where pancreatic amylase breaks down starch into disaccharides, which are then converted into monosaccharides and absorbed into the bloodstream.

Step-by-step explanation:

The process described in the question involves the digestion of carbohydrates that begins in the mouth and continues into the small intestine. During this process, pancreatic amylase breaks down starch and glycogen into maltose, a disaccharide. Maltase, sucrase, and lactase, enzymes found in the brush border of the small intestine, then convert maltose into glucose, sucrose into glucose and fructose, and lactose into glucose and galactose, respectively. These monosaccharides are subsequently absorbed into the bloodstream and transported to the liver. Therefore, the correct answer to which process involves the described steps is d) Carbohydrate digestion.
