Carbohydrates are made of monomers called:

• Amino acids

• Monosaccharides

• Nucleotides

• Fatty acids & Glycerol

Which of the following is NOT an example of a monosaccharide?

• Glucose

• Fructose

• Lactose

• Galactose

Because it is composed of TWO (2) monosaccharides, lactose is an example of a:

• Polysaccharide

• Trisaccharide

• Tetrasaccharide

• Disaccharide

Polysaccharides can serve one of two functions:

• Genetic instructions & Information storage

• Short-term energy storage & Structural support

• Long-term energy storage & Insulation

• Catalyzing chemical reactions & Cell-to-cell recognition

This carbohydrate functions to store short-term energy in the roots and seeds of plants:

• Chitin

• Cellulose

• Starch

• Glycogen

This carbohydrate functions to store short-term energy in the muscles and liver of animals:

• Chitin

• Cellulose

• Starch

• Glycogen

This carbohydrate functions to provide structural support in the cell walls of fungi and the exoskeletons of arthropods like insects, crustaceans & arachnids:

• Chitin

• Cellulose

• Starch

• Glycogen

This carbohydrate functions to provide structural support within the cell walls of plants and serves as the fiber in our diet:

• Chitin

• Cellulose

• Starch

• Glycogen

When animals eat a polysaccharide like starch, they digest it into individual glucose monomers through a reactions called:

• Hydrolysis

• Dehydration synthesis

• Condensation reaction

• Both dehydration synthesis & condensation reaction are correct
