NEET 2019 Biology question

How does steroid hormone influence the cellular activities?

(1)Changing the permeability of the cell membrane
(2)Binding to DNA and forming a gene-hormone complexCorrect
(3)Activating cyclic AMP located on the cell membrane
(4)Using aquaporin channels as second messenger

Answer: (2)

Solution

Steroid hormones are lipid soluble, so they cross the plasma membrane and bind to intracellular (cytoplasmic or nuclear) receptors. The hormone-receptor complex then interacts with the genome (DNA/chromatin), altering gene expression, and this changes cellular metabolism and function
