Question

1. glucose, fructose and galactose are all types of: *

a) monosaccharides
b) disaccharides
c) polysaccharides
d) oligosaccharides

1. in starches, the glucose units are joined together by: *

a) oligosaccharides
b) peptide bonds
c) alpha bonds
d) beta bonds

1. which of these foods would have the lowest glycemic index? *

a) crackers
b) white bread
c) rice

Explanation:

For question 1: Monosaccharides are the simplest form of carbohydrates and cannot be further broken down into simpler sugars. Glucose, fructose, and galactose are all single - sugar units.
For question 2: In starches, glucose units are linked by alpha - glycosidic bonds. Peptide bonds are in proteins, beta bonds are in cellulose (a different polysaccharide), and oligosaccharides are short chains of sugars (not the type of bond in starch).
For question 3: Among the given options, rice (especially whole - grain rice in some cases, but compared to crackers and white bread which are highly processed and have a high glycemic index) generally has a relatively lower glycemic index. Crackers and white bread are often refined and cause a more rapid spike in blood sugar.

Answer:

1. A. Monosaccharides
2. C. Alpha bonds
3. C. Rice
