Question

Which of the following regarding hormones is correct?
A)Progesterone is a polypeptide hormone.
B)Epinephrine is an amino acid.
C)Steroid hormones can enter cells and regulate translation.
D)Insulin is a polypeptide hormone.

Accepted Answer

Insulin is a polypeptide hormone, consisting of two chains of amino acids linked by disulfide bonds. Progesterone and steroid hormones are derived from cholesterol and are not polypeptides. Epinephrine is an amine hormone, derived from the amino acid tyrosine. Steroid hormones can enter cells and regulate gene expression, but not translation specifically.
