Exploring Carbohydrates

What is a monosaccharide?

• A monosaccharide is a lipid that stores energy in the body.

• A monosaccharide is a single sugar molecule, the simplest form of carbohydrates.

• A monosaccharide is a type of protein found in cells.

• A monosaccharide is a complex carbohydrate made of multiple sugar molecules.

Give an example of a monosaccharide.

• Fructose

• Sucrose

• Lactose

• Glucose

What is the general formula for monosaccharides?

• C6H12O6

• C5H10O5

• CnH2n-1On-1

• CnH2nOn

Define disaccharides and provide an example.

• Disaccharides are single sugars like glucose and an example is maltose.

• An example of a disaccharide is starch, which is made of multiple glucose units.

• An example of a disaccharide is lactose, which is composed of glucose and galactose.

• An example of a disaccharide is sucrose, which is composed of glucose and fructose.

What type of bond connects two monosaccharides in a disaccharide?

• hydrogen bond

• ionic bond

• peptide bond

• glycosidic bond

Name a common disaccharide and its components.

• Trehalose; components: glucose and sucrose

• Sucrose; components: glucose and fructose

• Maltose; components: glucose and glucose

• Lactose; components: glucose and galactose

What are polysaccharides and how are they formed?

• Polysaccharides are large carbohydrates formed by the polymerization of monosaccharides.

• Polysaccharides are formed by the breakdown of fats.

• Polysaccharides are proteins that help in digestion.

• Polysaccharides are simple sugars found in fruits.

List two examples of polysaccharides.

• Sucrose

• Starch, Cellulose

• Glucose

• Fructose

What is the primary function of carbohydrates in living organisms?

• To facilitate cellular communication.

• To act as a structural component in cell membranes.

• To store genetic information.

• The primary function of carbohydrates is to provide energy.

How do carbohydrates provide energy to the body?

• Carbohydrates are converted into proteins for energy.

• Carbohydrates are stored as fat and do not provide energy.

• Carbohydrates provide energy by being converted into glucose, which is used to produce ATP.

• Carbohydrates provide energy by being absorbed directly into the bloodstream without conversion.
