Question:

How does steroid hormone influence the cellular activities?

Changing the permeability of the cell membrane

Binding to DNA and forming a gene hormone complex

Using aquaporin channels as second messenger

Activating cycle AMP located on the cell membrane

Solution:

Correct option is B. Binding to DNA and forming a gene hormone complex. Steroid hormones directly enter into the cell and bind with intracellular receptors in the nucleus to form a hormone-receptor complex. The hormone-receptor complex interacts with the genome and affects cellular activity. So, the correct answer is 'Binding to DNA and forming a gene hormone complex'.
