Give the molecular formula of the

molecule that is removed when two

monosaccharides join together

• CO₂

• H₂O

• C

• H₂

• O₂

Which of the following is an example

of a monosaccharide?

• lactose

• sucrose

• glucose

• maltose

Which of the following is not an

example of a polysaccharide?

• starch

• cellulose

• glycogen

• galactose

What type of bond is formed between

two monosaccharides when they join

together to form a disaccharide?

• peptide

• phosphodiester

• glycosidic

• ester

• hydrogen

Glucose can be stored as the

polysaccharide starch in plant cells. What

polysaccharide acts as the primary unit of

glucose storage in animal cells?

• chitin

• alpha glucose

• glucagon

• glycogen

This carbohydrate is the primary

component of plant cell walls.

• Alpha-glucose

• Beta-glucose

• Glycogen

• Cellulose

This carbohydrate acts as a sugar-storage

component in animal cells.

• Starch

• Beta-glucose

• Cellulose

• Glycogen

What type of reaction occurs when two

or more monosaccharides join together?

• Reduction

• Substitution

• Condensation

• Hydrolysis

Which of the following best describes

the relationship between monosaccharides

and polysaccharides?

• Monosaccharides can be broken down to

  form polysaccharides.

• Monosaccharides can be joined together

  by bonds called polysaccharides.

• Polysaccharides have complementary

  binding sites to monosaccharides.

• Many monosaccharides can join

  together to form a polysaccharide

Which of the following is not a primary

function of carbohydrates in the human

body?

• Larger, complex carbohydrates can be

  broken down into fatty acids that can

  help make hormones.

• Carbohydrates act as storage molecules

  to help regulate blood glucose

  concentration.

• Simple carbohydrates can be used to

  build larger, more complex

  carbohydrates that can be used as cell

  components.

• Carbohydrates provide substrates that

  can be broken down in cellular

  respiration to release energy
