Question

Quizplus · Accepted Answer

Each target cell has its own unique signal transduction pathway that is determined by the receptor on the surface of the cell, which is further influenced by the cell's internal state and environment. As a result, the same peptide hormone may activate different pathways in different target cells, leading to a variety of responses.
