Signal transduction pathways initiate activation of transcription after specific
A) TH cell death.
B) ligand-receptor binding on the cell surface.
C) cytokines diffuse across the cytoplasmic membrane.
D) antigen-antibody binding.

Question

Quizplus · Accepted Answer

Signal transduction pathways are activated after ligand-receptor binding on the cell surface. This binding triggers a cascade of events that ultimately leads to activation of transcription factors and initiation of transcription. TH cell death and antigen-antibody binding are not directly related to signal transduction pathways, while cytokines may play a role in signaling but do not themselves initiate activation of transcription.
