ENDOCRINE SYSTEM - Hormone Regulation & Receptors Flashcards
1
Q
What is up-regulation?
A
Target cells increase receptors to enhance hormone sensitivity (e.g., uterus for oxytocin during childbirth).
2
Q
What is down-regulation?
A
Target cells decrease receptors to reduce sensitivity (e.g., insulin receptors in Type II diabetes).
3
