Question
Chapter 9, Problem 1A
Summary Introduction
Introduction:
The steroid hormones are lipid soluble molecules that have the capability to cross the plasma membrane. The receptors for these hormones are located inside the cytoplasm of the cell (intracellular receptors).

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.
Steroid hormones
a. can diffuse through the membrane without a carrier.
b. have a direct effect on gene expression.
c. bind to membrane receptors.
d. Both a and b are correct.
what happens when an agonist, instead of the endogenous (natural) hormone binds to the hormone recepters of a target.
A. an antagonist is necessary to remove the agonist
B. the agonist blockd any response in the target cell
C. the cell responds by producing its own hormone
D. transcription factors are blocked from binding to the promotor region
E. the agonist has the same effect as the endogenous hormone.
