Question

Quizplus · Accepted Answer

Steroid hormones are lipid-soluble and can diffuse across the plasma membrane of target cells. Once inside the cell, they bind to receptors in the cytoplasm or nucleus, forming a hormone-receptor complex that can directly initiate or alter the expression of genes, ultimately leading to changes in protein synthesis and cellular function.
