Question
Cells contain different types of biomolecules, each with a structure related to its specific function. Which statements correctly describe how the structure and function of carbohydrates, lipids, proteins, and nucleic acids relate to the cell? Select THREE correct answers.

1) Phospholipids are amphipathic (hydrophilic head, hydrophobic tails) and spontaneously form bilayers — the structural basis of cellular membranes.
- The head/tail chemistry drives self‑assembly into a barrier that controls passage of molecules.
2) Cellulose has β‑1,4 glycosidic linkages that produce straight chains which hydrogen‑bond to one another, giving plant cell walls high tensile strength.
- The linkage and orientation (β rather than α) determine the rigid, structural role.
3) A protein’s specific three‑dimensional shape, determined by its amino‑acid sequence (primary structure) and stabilized by secondary/tertiary/quaternary interactions, dictates its function (enzymes, transport, structural roles, etc.).
