Question
Steroid hormones act on target cells bya. initiating second messenger activity.b. binding to membrane proteins.c. initiating DNA transcription.d. activating enzymes.e. binding to membrane lipids.
Step 1
Steroid hormones are a type of hormone that includes testosterone and cortisol. These hormones play various roles in the body, such as activating the development of puberty in males (in the case of testosterone). Show more…

Steroid hormones such as estrogen act on target cells by a. initiating second-messenger activity b. binding to membrane proteins. c. initiating gene expression. d. activating enzymes. e. binding to membrane lipids
_________hormones enter target cells and bind to intracellular receptors, whereas _____________hormones bind to cell membrane receptors and never enter the target cells. a. Nonsteroid ... steroid c. Steroid ... nonsteroid b. Protein ... peptide d. Steroid ... carbohydrate
The action of steroid hormones is different from that of peptide hormones because: a. 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.
