Exploring Carbohydrates Structure

What is the basic building block of carbohydrates?

• Disaccharides

• Polysaccharides

• Monosaccharides

• Glycerol

Describe the general formula for monosaccharides.

• (C5H10O5)n

• (C6H12O6)n

• The general formula for monosaccharides is (CH2O)n.

• (C3H6O3)n

What type of bond connects monosaccharides in disaccharides?

• hydrogen bond

• peptide bond

• ionic bond

• glycosidic bond

Name two common disaccharides and their monosaccharide components.

• Fructose (glucose + sucrose)

• Sucrose (glucose + fructose), Lactose (glucose + galactose)

• Galactose (glucose + glucose)

• Maltose (glucose + glucose)

What is the difference between alpha and beta glucose?

• Alpha glucose is a type of starch, while beta glucose is a type of cellulose.

• Alpha glucose has a -OH group on C2, while beta glucose has it on C1.

• Alpha glucose is more soluble in water than beta glucose.

• Alpha glucose has the -OH group on C1 below the ring, while beta glucose has it above the ring.

Explain the structure of starch and its function in plants.

• Starch is a simple sugar used for immediate energy.

• Starch is a polysaccharide made of glucose units, functioning as an energy storage molecule in plants.

• Starch is a lipid that provides structural support in plant cells.

• Starch is a protein that helps in photosynthesis.

What is glycogen and where is it primarily stored in the body?

• Glycogen is stored only in the kidneys.

• Glycogen is primarily found in the skin.

• Glycogen is a type of protein stored in the heart.

• Glycogen is primarily stored in the liver and muscles.

Describe the structural differences between cellulose and starch.

• Cellulose is a branched polymer, while starch is a linear polymer.

• Both cellulose and starch have linear chains of alpha-glucose.

• Cellulose is made of alpha-glucose, while starch is made of beta-glucose.

• Cellulose has linear chains of beta-glucose, while starch has branched chains of alpha-glucose.

What role do carbohydrates play in cellular respiration?

• Carbohydrates are converted into fats during cellular respiration.

• Carbohydrates are only used for structural support in cells.

• Carbohydrates provide glucose, which is a primary energy source in cellular respiration.

• Carbohydrates are a source of protein in cellular respiration.

How do the structures of carbohydrates influence their function in living organisms?

• The structures of carbohydrates influence their function by determining their solubility, digestibility, and role in energy storage or structural support.

• The structure of carbohydrates has no impact on their function.

• Carbohydrates are only involved in the formation of nucleic acids.

• Carbohydrates are primarily used for protein synthesis.
