Question

Quizplus · Accepted Answer

Cell surface receptors are proteins located on the surface of the cell membrane that can bind to extracellular signals such as hormones, growth factors, or neurotransmitters. Upon binding, they convert the extracellular signal into an intracellular one, triggering a cellular response. Peptide hormones and growth factor proteins can bind to these receptors, but they themselves are not the molecules that convert extracellular signals into intracellular ones. Genes are not involved in this process.
