Which bone cell secretes hydrochloric acid to help dissolve bone minerals and collagenase, thus aiding in the digestion of collagen?
A)Osteocytes
B)Osteoblasts
C)Osteoclasts
D)Osteophytes

Question

Quizplus · Accepted Answer

Osteoclasts bind to the bone surface of cell attachment proteins called integrins. They bring about resorption of bone by secreting hydrochloric acid and cathepsin K (a protease enzyme) that help dissolve bone minerals and collagenase, which aids in digesting collagen, along with the action of cytokines. Osteocytes are the most abundant cells in bone. Osteoblasts are bone forming cells. Osteophytes are bony outgrowths, otherwise known as bone spurs.
