Which chemical stimulates the interaction between these proteins? a. cholinesterase b. calcium c. potassium d. ionium What is one important difference between organizing and activating effects of hormones? a. Organizing effects take place during an early sensitive period b. Activating effects are more permanent c. Activating effects take place only in the brain d. Organizing effects take place only in the gonads

In relation to Cushing’s Syndrome, a method that some scientists have used to treat the disease is to use small molecules that bind to, but do not activate, MC2R. This type of molecule is considered an antagonist. How can an antagonist bind to the same receptor as ACTH but not activate it ? a. The antagonist binds covalently while ACTH binds non covalently b. The antagonist is only partially complimentary to the binding pocket of MC2R c. The antagonist binds to ACTH and blocks it from binding to the receptor properly d. The antagonist is the exact same structure as ACTH but since it is synthetic it doesn’t work

The action of steroid hormones is different from that of peptide hormones becausea. peptide hormones must enter the cell to begin action, whereas steroid hormones must begin action on the external surface of the cell membrane.b. steroid hormones must enter the cell to begin action, whereas peptide hormones must begin action on the external surface of the cell membrane.c. peptide hormones produce a hormone receptor complex that works directly on the DNA, whereas steroid hormones cause the release of a secondary messenger that triggers enzymes.d. None of these answers is correct.
A Moving to the next question prevents changes to this answer. Question 1 What is unusual about the receptor for steroid hormones? A. The receptor is located in the cytoplasm but can enter the nucleus once bound to ligand. B. The receptor is embedded in the plasma membrane C.
