Question

Choose the correct answer from the alternatives given.
Peptide hormones:

• A. are received by a receptor located in the plasma membrane
• B. are received by a receptor located in the cytoplasm
• C. bring about the transcription of DNA
• D. both (a) and (c)

Answer 1

The correct option is A are received by a receptor located in the plasma membrane

Hormones produce their effects on target tissues by binding to specific proteins called hormone receptors located in the target tissue only. Hormone receptors present on the cell membrane of the target cells are called membrane-bound receptors and the receptors present inside the target cell are called intracellular receptors, mostly nuclear receptors (present in the nucleus.

So the correct answer is are received by a receptor located in the plasma membrane.
