Question

Why is the structure of molecule important to its function?

Answer 1

A Molecule's Biological Function is Related to its Shape. Each molecule has a characteristic size and shape that determines its function in the living cell. The shapes of molecules are determined by the positions of the atoms' orbitals. When an atom forms covalent bonds, the orbitals in its valence shell are rearranged that’s your answer

Answer 2

In materials of molecular structure, the nature of intermolecular and intramolecular bonds has a decisive influence on their characteristics and properties. Characteristics such as melting and boiling points, mechanical strength and hardness depend on the type of such bonds.
