Question

The receptor for protein hormones are present on

• A. Nucleus
• B. Endoplasmic reticulum
• C. Cytoplasm
• D. Cell-surface

Answer 1

The correct option is D Cell-surface

Hormone binds to specific receptors called as hormone-receptors. These hormone receptors may be present on the cell surface or inside the cell, depending on the activity and pathway followed by the hormone for stimulation. Peptide hormones have receptors which are present on the cell surface. These receptors are embedded in the plasma membrane and so, called as the transmembrane receptors.

So, the correct answer is option D.
