QUESTION 40
Steroid hormones do not:
O bind to receptors inside the cell, travel to the nucleus, and bind to DNA to influence gene transcription
O pass through cells' plasma membranes
O use second messenger systems
O undergo production by the gonads and adrenal cortex

Kunduz · Accepted Answer

The correct answer is (c) use second
messengers.
Steroid hormones are made of lipids, such as
phospholipids and cholesterol. They are fat
soluble, so they can diffuse across the plasma
membrane of target cells and bind with
receptors in the cytoplasm of the cell. The
steroid hormone and receptor form a complex
that moves into the nucleus and influences the
expression of genes, essentially acting as a
transcription factor.
Non-steroid hormones are made of amino
acids. They are not fat soluble, so they
cannot diffuse across the plasma membrane
of target cells. Hence they need to use
second messengers and steroid hormones
do not use any second messengers.
