Carbohydrates

Question 1

Carbohydrates

Answer 1

Type of food that provide a source of energy for the body

• quick fuel source
• short-term energy storage

Question 2

Simple Carbohydrate

Answer 2

Monosaccharides are monomers of carbohydrates

-are sugars with 3-7 carbon atoms

Question 3

Hexose Carbohydrates

C6H12O6

Answer 3

• Glucose
• Fructose
• Galactose

They are all monomers and all have the same chemical formula, but their shapes and arrangement of atoms differ.

Question 4

Disaccharides

Answer 4

Monomer +(dehydration reaction) monomer = disaccharide + 1 H2O

Question 5

Maltose

Answer 5

Glucose + Glucose = _____ + 1 H2O

Question 6

Sucrose

Answer 6

Fructose + Glucose = ________ + 1 H2O

Question 7

Lactose

Answer 7

Galactose + Glucose = _________ + 1 H2O

Question 8

Functional group of: Monosaccharide

Answer 8

Carbon ring completed by Oxygen

Question 9

Polymer of: Carbohydrate

Answer 9

Polysaccharide

• glycogen
• starch
• cellulose

Question 10

Starch

Answer 10

Polysaccharide of glucose molecules in a straight chain, somewhat branched.

Storage form of glucose in plants.

Question 11

Glycogen

Answer 11

Polysaccharide of glucose molecules in a highly branched chain of glucose molecules.

Storage form of glucose in animals.

Stored temporarily in the liver (and muscle cells) so there is a constant ratio of glycogen in the bloodstream.

Question 12

Cellulose

Answer 12

Polysaccharide of glucose molecules in a straight chain of glucose molecules.

Lends rigidity to plant cell walls (as long as they receive an adequate supply of water).

Linkage btwn glucose molecules go up then down (H-bonds) which the human body cannot process (can only process H-bonds going down = glycogen and starch).

Used as roughage and excreted through the system.
