What is the effect of hormone-receptor complex formation on target tissues?
Options
- AIt leads to the formation of second messengers
- BIt regulates gene expression or chromosome function
- CIt leads to certain biochemical changes in the target tissue
- DIt leads to physiological and developmental effects
Correct answer
C. It leads to certain biochemical changes in the target tissue
Step-by-step solution
Hormones produce their effects on target tissues by binding to specific proteins called hormone receptors located in the target tissues 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). Binding of a hormone to its receptor leads to the formation of a hormone-receptor complex (Figure 19.5 a, b). Each receptor is specific to
