Answer:
The correct answer is A.
Explanation:
An osteoclast is large multinucleated cell present in the bone. Its main function is bone resorption, which occur when the osteoclasts secret hydrogen ions and many enzymes. As a result, bone matrix is digested by them. The most important enzyme is the protease cathepsin K, which degrades collagen.
Cathepsin K is regulated by parathormone, calcitonin and growth factor interleukin 6.
Matrix digestion is key during <u>bone fractures</u>, because it allows the repair and remodeling of the bone. But when this action is excessive, it can lead to osteoporosis (loss of bone density).
