Dietetic Technician Practice Test

The end process of sucrose digestion is:

1. glucose and fructose

2. glucose and galactose

3. glucose and mannose

4. 2 glucose molecules

The correct answer is: glucose and fructose

The end process of sucrose digestion results in glucose and fructose, making the selected answer accurate. Sucrose, commonly known as table sugar, is a disaccharide composed of one glucose molecule and one fructose molecule. During digestion, the enzyme sucrase (or invertase) breaks the bonds that connect these two monosaccharides. As a result, upon the enzymatic action, sucrose is hydrolyzed into its constituent sugars—glucose and fructose—both of which can be readily absorbed into the bloodstream through the intestinal lining. This understanding is essential for comprehending carbohydrate metabolism and the nutritional implications of consuming sucrose. The other options presented do not reflect the correct monosaccharide products that arise from sucrose digestion, thereby highlighting why they are not correct in this context.
