Protein channels.

Explanation: the phospholipid bilayer is impermeable to large polar molecules like glucose, so they cross via membrane proteins — e.g., carrier/transport proteins (GLUTs for glucose) or channel proteins, sometimes coupled to active transport (pumps) if energy is needed. Lipid pathways are for small nonpolar molecules only.
