6. If a eukaryotic cell's cytoskeleton were to be disrupted, what immediate
effect might this have on the cell?
Improved nutrient absorption
Increased energy production
Enhanced cell division

7. Describe the role of glucose in cellular energy storage and metabolism.
Glucose is involved in the synthesis of proteins.
Glucose serves as a primary energy source for cells and is stored as
glycogen in animals.
, Glucose is a structural component of cell membranes.
Glucose is a type of lipid that stores energy.
8. Describe why compounds with a molecular mass of 1,000 g/mol or more are
classified as macromolecules.
Compounds with a molecular mass of 1,000 g/mol or more are
classified as macromolecules because they are always proteins.
Compounds with a molecular mass of 1,000 g/mol or more are
classified as macromolecules due to their high solubility in water.
Compounds with a molecular mass of 1,000 g/mol or more are
classified as macromolecules since they are always found in living
organisms.
Compounds with a molecular mass of 1,000 g/mol or more are
classified as macromolecules because they consist of large
numbers of atoms and exhibit complex structures, which are
essential for biological functions.

together?
Mixture
Compound
Aggregate
Complex
10. Which of the following is true about the functional groups in
macromolecules?
