Refer to the figure showing two hormones. It is most likely that the two hormones are
A) steroid hormones, and that 1 is a male sex hormone and 2 is female sex hormone.
B) amine hormones, and that 1 can be converted into 2.
C) made from cholesterol, and that 2 is a form of vitamin D created from 1.
D) small protein hormones, are water-soluble, and therefore cannot diffuse through membranes.
E) large protein hormones that bind to cell surface receptors, affecting cells through second messengers.

Quizplus · Accepted Answer

The two hormones shown are both derived from the amino acid tyrosine, indicating that they are likely amine hormones. Additionally, the conversion of 1 into 2 (or vice versa) suggests that they may be related in their function or regulation.
