The statement that best describes the concept of the relationship between the structure of macromolecules and the functions they perform in living cells is:
**B. the active site of a protein enzyme precisely fits the shape of its substrate molecules.**
This statement emphasizes how the specific structure of an enzyme (its active site) is critical for its function, as it must match the shape of the substrate it acts upon. This concept of "specificity" in molecular interactions is fundamental to understanding how macromolecules function in biological systems.
