Which term refers to the biochemical events leading to physiological changes?

• A. Solute
• B. Mechanism of action
• C. Vials
• D. Solvent

Answer: (B)

The term describes how a drug produces its effects at the molecular level—the sequence of biochemical events that leads to physiological changes. This is the mechanism of action: it explains how the drug interacts with targets such as receptors or enzymes, alters signaling pathways, and ultimately causes the observed bodily responses. Solute and solvent refer to substances in a solution and don’t address biological effects, while a vial is simply a container. So the mechanism of action best captures the biochemical events translating to physiological change.
