Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
When we eat disaccharides, our cells do what first before energy is obtained?
A
make the disaccharide a polysaccharide
B
break the disaccharides down to monosaccharides
C
leave the disaccharides as is, and obtain energy
D
throw the disaccharide out, because we can’t use it.
Explanation: 

Detailed explanation-1: -As disaccharides travel through the body they are broken down into simple sugars, or monosaccharides, by a process called hydrolysis. This process is facilitated by enzymes called maltases, sucrases, and lactases.

Detailed explanation-2: -The process of hydrolysis in the small intestine breaks down the disaccharides into monosaccharides.

Detailed explanation-3: -The goal of carbohydrate digestion is to break down all disaccharides and complex carbohydrates into monosaccharides for absorption, although not all are completely absorbed in the small intestine (e.g., fiber). Digestion begins in the mouth with salivary amylase released during the process of chewing.

Detailed explanation-4: -Two simple sugars (monosaccharides) together form a disaccharide. Dietary disaccharides include maltose (a product of the digestion of starch), sucrose (table sugar), and lactose (the sugar in milk). These disaccharides must be broken down by enzymes into two simple sugars so that they can be absorbed by the intestine.
