Biomolecule - Advanced Q's

Carbohydrates and lipids share which cellular functioning?

• Hormone production

• Structural support of cell walls

• Provides energy

• Catalyst for chemical reactions

Answer explanation

Carbohydrates provide quick energy. Lipids provide long term energy.

The human body uses specialized proteins to speed up chemical reactions. These proteins are called enzymes. Without enzymes, the reactions in the body would happen too slowly to keep you alive. Enzymes are made during protein synthesis, which occurs at a cell's ribosomes.

Which biomolecule provides the instructions to build enzymes?

• Carbohydrates

• Lipids

• Nucleic Acids

• Proteins

Answer explanation

The function of nucleic acids (DNA) are to provide genetic information and instructions.

Lactose is a sugar found in dairy products. The body converts it into a molecule that can be used to make ATP energy.

What type of biomolecule is lactose?

• Carbohydrate

• Lipid

• Nucleic Acid

• Protein

Monomers are small molecules that can join together to make larger molecules called polymers. Nearly all of the large molecules in our bodies are a kind of polymer.

Which of the examples are monomers? Select all that apply.

• Nucleotide

• Glucose

• Starch

• Protein

Answer explanation

Nucleotide = Monomer of Nucleic Acid

Glucose = Monomer of Carbohydrate

Which of the following are monomer function? Select all that apply.

• Building block

• Enzyme activity

• Usable energy

• Structural support

Answer explanation

Monomers are single building blocks. Monomers, such as glucose, are usable energy.

Which of the following is NOT a polymer function?

• Energy storage

• Exoskeleton

• Information Storage

• Building block
