Question

Quizplus · Accepted Answer

Ligands are chemical messengers that bind to specific receptors on cell surfaces and trigger a response in the cell. Examples of ligands include hormones and neurotransmitters. Caveolae are small invaginations in the cell membrane, cell adhesion molecules are proteins that facilitate cell-cell interactions, and flagella are threadlike structures that enable cells to move. None of these options accurately describe the function of ligands.
