Testosterone functions inside a cell by group of answer choices binding with a receptor protein that enters the nucleus and activates specific genes coordinating a phosphorylation cascade that increases spermatogenesis acting as a signal receptor that activates tyrosine kinases acting as a steroid signal receptor that activates ion channel proteins

Testosterone functions inside a cell by binding with a receptor protein that enters the nucleus and activates specific genes.

Explanation:

Testosterone is a steroid hormone because it is synthesized from cholesterol.Testosterone is released from the leydic cells.

  The most active form of testosterone is called  dihydrotestosterone(DHT) .Once bound to the receptor testosterone builds a complex with the receptor.

 The receptor hormone complex then transported to the nucleus of the target cell and interacts with specific nucleotide sequence of target cell"s DNA molecule.These specific nucleotide sequence is termed as hormone responsive elements.      

Answer:

Testosterone functions inside a cell by A: binding with a receptor protein that enters the nucleus and activates specific genes .

Explanation:

"Testosterone” is a primary "male" sex hormone and a natural "anabolic steroid". It plays an important role in developing male reproductive tissues. It also increases body and muscle mass, growth of body hair. It also regulates sperm production.

Testosterone diffuses through cell membrane. It is a type of “androgen” which is mainly produced by the testicles in cells called the Leydig cells. It enters the cell where it binds with DNA and initiates transcription. It is also a steroid hormone because it is derived from cholesterol.
