Carbohydrate Worksheet Answer Key
1. What is the monomer for carbohydrates?
Glucose, Monosaccharide or CH2O
2. What are the two polymers for carbohydrates?
Disaccharides and polysaccharides
3. What is the chemical formula for monosaccharides?
C6H12O2 or C5H10O5
4. What are three familiar monosaccharides that are considered as hexoses?
Glucose, Galactose and Fructose
5. Draw the chemical structure in ring form for glucose?
6. What are disaccharides?
Disaccharides are two monosaccharides bonded together
7. List three different disaccharides.
Sucrose, Lactose, Maltose
8. What is the chemical formula for disaccharides?
C12H22O11
9. Why is this formula have two less hydrogen and one less oxygen atom if two
monosaccharides were added together?
Because it undergoes dehydration synthesis to lose a water molecule (H2O)
10.What is the process called when one molecule of water is ripped off to make a
disaccharide?
Dehydration synthesis
11.What is the process called when one disaccharide has a molecule of water added to
it and creates two separate monosaccharides?
Hydrolysis
12.What are polysaccharides?
Polysaccharides are 3 or more monosaccharides linked together
13.Give 2 examples of polysaccharides?
Glycogen, Starch, or Cellulose
14.When five glucoses (monosaccharides) are placed together to begin making a
polysaccharide, how many molecules of water would be formed?
Four
15.What is that process called when these water molecules are formed by the linking of
monomers to make polymers?
Dehydration synthesis
16.What is the opposite to dehydration synthesis?
Hydrolysis
