MULTIPLE CHOICE

 

1. The primary function of carbohydrates in the body is to provide

a.	sweetness.
b.	satiety.
c.	energy.
d.	dietary fiber.

 

 

ANS:  C

The most important function of carbohydrates in the body is to provide energy. Unrefined sources of carbohydrate do provide dietary fiber, but refined carbohydrates do not. Similarly, unrefined carbohydrates may add to satiety, but refined carbohydrates contribute less to satiety than do protein and fat. Simple carbohydrates provide sweetness; this is pleasant but not essential to the body.

3. The sweetness in a banana comes mostly from

a.	fructose and sucrose.
b.	fructose and glucose.
c.	glucose and maltose.
d.	maltose and sucrose.

 

 

ANS:  A

The most common sugars found naturally in fruits such as a banana are fructose and sucrose. It may also contain some glucose, but this contributes less to the sweetness. Fructose is the sweetest of the sugars, and so it contributes most to the sweetness. Maltose is found only in germinating grains or as a product of partial starch digestion in the gut.
