The cell organelles that synthesize organic matrix substances in bone formation are:
A) mitochondria and Golgi apparatus.
B) ribosomes and Golgi apparatus.
C) endoplasmic reticulum and ribosomes.
D) endoplasmic reticulum and Golgi apparatus.

Question

Quizplus · Accepted Answer

The endoplasmic reticulum (ER) and Golgi apparatus work together to synthesize and modify proteins that are necessary for bone formation. The ER is responsible for protein synthesis, while the Golgi apparatus modifies and packages the proteins for transport to the cell surface or secretion. In the case of bone formation, the proteins synthesized by the ER and Golgi apparatus are organic matrix substances such as collagen, which provide the structure and strength of bone tissue. Therefore, D is the best choice.
