Question

Quizplus · Accepted Answer

Testosterone is a steroid hormone that enters a cell and binds with a specific receptor protein, forming a hormone-receptor complex. This complex then enters the nucleus and activates or deactivates specific target genes, resulting in changes in the cell's behavior and physiology. This process is known as gene expression regulation.
