$FSH$

Vedclass · Answer

(D) The diagram illustrates the mechanism of action of protein/peptide hormones that are not lipid-soluble and therefore cannot enter the target cell. These hormones bind to specific receptors located on the surface of the plasma membrane,forming a hormone-receptor complex. This binding triggers the generation of second messengers (such as $cAMP$ or $Ca^{++}$) within the cell,which then regulate cellular metabolism and physiological responses. Among the given options,$FSH$ (Follicle Stimulating Hormone) is a peptide hormone that acts via this membrane-bound receptor mechanism. Insulin also acts via membrane receptors,but $FSH$ is a classic example often associated with this specific diagram in $NCERT$ textbooks.
