B) bind to DNA and cause changes in transcription
C) cannot pass through cell membranes
D) are produced in the interstitial fluid

Question

Quizplus · Accepted Answer

Hormones that bind to plasma membrane receptors cannot pass through cell membranes because they are usually large or polar molecules that cannot easily pass through the hydrophobic lipid bilayer of the membrane. Examples of such hormones include epinephrine, norepinephrine, and peptide hormones such as insulin and glucagon. Steroid hormones, on the other hand, are able to pass through cell membranes due to their lipid-soluble nature and bind to intracellular receptors, ultimately leading to changes in gene expression via alterations in transcription.
