Question

Bone-forming cells that produce collagen and proteoglycans and release matrix vesicles are ___________.

A. Osteoclasts
B. Osteocytes
C. Chondroblasts
D. Osteoblasts

Answer 1

Osteoblasts are bone cells that produce collagen, proteoglycans, and matrix vesicles. They are responsible for forming new bone by synthesizing and secreting the organic part of the bone matrix and releasing calcium and phosphate ions.

Step-by-step explanation:

Osteoblasts are bone cells that produce collagen and proteoglycans, and release matrix vesicles. They are responsible for forming new bone by synthesizing and secreting the organic part of the bone matrix. Osteoblasts also release calcium and phosphate ions for mineralization of the matrix.
