2 points Which of the following statements is true Protoin homones can easily pass through the plasma membrane d to nuclear hormone receptor and activate DNA for action Protein hormones do not bind to nuclear hormone receptor and act to DNA for action but these molecules can sell dimuse across the plasma membrane Sterod hormones have to brd to a Gprolen receptor onthe play: Steroid hormones can easily pass through the plasma membrane d to nuclear hormone neceptor t membrane actate a secondry messenger and tenactate DNA freon for action Question 15 o Mong to another question wil save tes response.

Explanation / Answer

Protein hormones are water soluble and cannot freely diffuse into the cell. They bind to specific receptors on the plasma membrane and then exert their action through secondary messengers like cAMP or Ca++.

Steroid hormones are lipid soluble and easily pass through cell or nuclear membrane. These hormones then bind to specific receptors, either in the nucleus or cytoplasm, and then this hormone-receptor complex binds to specific regions of the DNA and exert their action by promoting or inhibiting transcription.

Answer- D- Steroid hormones can easily pass through the plasma membrane, bind to nuclear hormone receptor and activate DNA for action.
