When a Steroid Hormone and a Peptide Hormone Exert Similar

question 22

Multiple Choice

When a steroid hormone and a peptide hormone exert similar effects on a population of target cells, then

• A) the steroid and peptide hormones must use the same biochemical mechanisms.
• B) the steroid and peptide hormones must bind to the same receptor protein.
• C) the steroid hormones affect the synthesis of effector proteins, whereas peptide hormones activate effector proteins already present in the cell.
• D) the steroid hormones affect the activity of certain proteins within the cell, whereas peptide hormones directly affect the processing of mRNA.
• E) the steroid hormones affect only the release of proteins from the target cell, whereas peptide hormones affect only the synthesis of proteins that remain in the target cell.
