Question

Which site responds to a hormone?

• A. Receptor
• B. Effector
• C. Affector
• D. Substrate

Answer 1

The correct option is A Receptor

• Receptors are specific proteins located on target tissues to which specific hormones bind to produce their effect.
  
• Binding of a hormone to its receptor leads to the formation of a hormone-receptor complex. Formation of Hormone-Receptor complex leads to certain biochemical changes in the target tissue.
  
• Hence Receptor site responds to a hormone.
• So, the correct answer is 'Receptor'.
