How does steroid hormone influence the cellular activities?
- AChanging the permeability of the cell membrane
- BBinding to DNA and forming a gene-hormone complex
- CActivating cyclic AMP located on the cell membrane
- DUsing aquaporin channels as second messenger
Solution & Step-by-step Explanation

Steroid hormones are lipid-soluble and can cross the plasma membrane. They typically bind to intracellular receptors (often in the nucleus). The hormone-receptor complex then binds to specific DNA sequences (Gene-hormone complex) to regulate gene expression and protein synthesis.
