4 Biomolecules and Enzymes Pre-Assessment

Carbohydrates are more easily metabolized than lipids. However, on a gram-for-gram basis lipids provide cells with more —

• Nitrogen

• Proteins

• Structure

• Energy

Which type of molecule do animals use for energy storage and insulation?

• Nucleic Acids

• Carbohydrates

• Lipids

• Proteins

Baby food manufacturers sometimes use a protease in their food products. A protease catalyzes the breakdown of the proteins in these foods, making digestion easier for infants.

A protease is what type of molecule?

• Enzyme

• Lipid

• Hormone

• Carbohydrate

Enzymes play a key role in many biochemical processes. What is their most common role in these reactions?

• to speed up the reaction

• to slow down the reaction

• to begin the reaction

• to finalize the reaction

Unknown #3 is most likely which of the following biomolecules?

• Carbohydrate

• Lipid

• Protein

• Nucleic Acid
