Question

which macromolecule stores genetic information? *
carbohydrates
lipids
nucleic acids
proteins

which macromolecule is important in making and repairing muscles? *
carbohydrates
nucleic acids
proteins
lipids

what process is used to bond two monomers together? *
hydrolysis
glycolysis
dehydration synthesis
krebs cycle

Explanation:

Identify genetic information storage

Using the Macromolecule Classification knowledge point

• Nucleic acids (DNA and RNA) store and transmit genetic information.
• Carbohydrates provide energy, lipids store energy/form membranes, and proteins perform cellular work.

Identify muscle building and repair macromolecule

Using the Macromolecule Classification knowledge point

• Proteins are the primary structural components of muscle tissues (actin and myosin).
• They are essential for building, maintaining, and repairing body tissues.

Identify the monomer bonding process

Using the Dehydration Synthesis knowledge point

• Bonding monomers together requires removing a water molecule to form a covalent bond.
• This process is dehydration synthesis.
• Hydrolysis breaks bonds using water, while glycolysis and the Krebs cycle are metabolic pathways for energy production.
