ozzi

Answer:

The correct answer is option B. It bind to a receptor in the plasma membrane.

Explanation:

Hormones can be aminoacid based hormones (peptide or amine) or the steroid base hormones on the basis of their nature. Amino acid based proteins are molecules that are proteins,

Peptide hormones are the protein or peptide molecule that release in blood by the exocytosis in the form of preprohormones that mature later and bind to the receptor present on the surface of the plasma membrane of the target cell. The binding of the peptide hormone to the receptors a secondary messenger shows up in the cytoplasm.

Thus, the correct answer is option B. It binds to a receptor in the plasma membrane.
