Question

Quizplus · Accepted Answer

Protein-based hormones typically exert their effects by binding to receptors on the surface of a cell, which then activates enzymes within the cell to carry out specific functions. This process is part of signal transduction, where the binding of the hormone to its receptor triggers a cascade of events inside the cell, leading to a physiological response.
