Explanation:
Detailed explanation-1: -D) 3, 4, 2, 1 . Reception-transduction-amplification-response. (signal transduction pathways occur in cellular level, reception is when particular ligand binds to receptor in cell membrane, which cause tr…
Detailed explanation-2: -What are the four steps of signal transduction? (1) signal molecule binds to receptor that (2) activates a protein that (3) creates second messengers that (4) creates a response.
Detailed explanation-3: -Depending on the ligand’s origin (from the same cell, from the neighbour cell or from far distance), recptor-ligand interaction and signaling pathway activation is classified into four different types: autocrine, endocrine, paracrine and juxtacrine.
