Explanation
The endoplasmic reticulum performs several key roles, including transport of materials within the cell, providing mechanical support to the cytoplasm, and synthesizing proteins, lipids, and other molecules including glycoproteins. Nerve impulse conduction, by contrast, is a function of the neuron's plasma membrane and its ion channels, not of the endoplasmic reticulum itself.
