Which signal molecule diffuses through the plasma membrane to ultimately bind nuclear receptors and influence transcription?
A) Estrogen
B) Nitric oxide
C) Cadherins
D) Nerve growth factor

Question

Quizplus · Accepted Answer

Estrogen is a steroid hormone that can diffuse through the plasma membrane and bind to nuclear receptors, leading to changes in gene expression. Nitric oxide is a gaseous signaling molecule that does not typically diffuse through the plasma membrane, and cadherins are cell adhesion molecules that do not directly influence transcription. Nerve growth factor is a protein that acts on cell surface receptors, but does not bind to nuclear receptors to influence transcription.
