Refer to the figure showing the signal transduction pathway that is initiated by the binding of cortisol to its receptor. Based on the figure, which can you conclude about this signal transduction pathway?
A) The cortisol receptor is a protein kinase receptor.
B) Cortisol is a polar molecule.
C) The cortisol-receptor complex influences gene expression.
D) Cortisol binds to a cell membrane receptor.
E) The signal transduction pathway involves a G protein.

Quizplus · Accepted Answer

The figure shows that after the cortisol-receptor complex is formed, it enters the nucleus and binds to DNA, suggesting that it influences gene expression. Therefore, choice C is the correct answer. The figure does not provide evidence for choices A, B, D, or E.
