Question

Quizplus · Accepted Answer

Steroid hormones are able to pass through the cell membrane due to their lipid-soluble nature. Once inside the cell, they bind to specific receptors in the cytoplasm which then translocate into the nucleus and bind to specific DNA sequences. This results in the initiation of gene expression and the production of new proteins that affect cell function.
