Question

practice it what is the role of osteoblasts? to generate electrical impulses for muscle contraction to produce and secrete digestive enzymes to synthesize and deposit new bone tissue to regulate calcium levels in the blood to break down and remove old bone tissue

Explanation:

Osteoblasts are bone - forming cells. Their main function is to synthesize and deposit new bone tissue by secreting the organic components of the bone matrix and facilitating the mineralization process. They are not involved in generating electrical impulses for muscle contraction, producing digestive enzymes, regulating blood calcium levels (that's mainly parathyroid and calcitonin), or breaking down old bone tissue (that's osteoclasts).

Answer:

To synthesize and deposit new bone tissue
