Question

Quizplus · Accepted Answer

The sequence of events between the binding of an extracellular messenger to a receptor and the cellular responses is called a signal transduction pathway. It involves a series of biochemical steps that ultimately lead to the cellular response. Homeostatic reactions and physiological reflexes are broader terms that can include multiple pathways and systems, while a reflex arc is a specific neural pathway for reflex responses.
