What is the role of hormones in target tissue metabolism and physiological functions?
Options
- AHormones stimulate target tissue metabolism and physiological functions
- BHormones inhibit target tissue metabolism and physiological functions
- CHormones regulate target tissue metabolism and physiological functions
- DHormones do not have any effect on target tissue metabolism and physiological functions
Correct answer
C. Hormones regulate target tissue metabolism and physiological functions
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
