Answer:

Osteoblast, osteocytes and osteoclasts are responsible for breaking down bone during remodeling.

Explanation:

The process which is responsible during bone formation in equally in initial and later stages of remodelling, they are the bigger cells which are responsible for the synthesis and mineralisation of bone. Osteocytes are the rich in cells in the bone tissue, which is helpful in detection of the mechanical loading, also manages the in bone formation and bone resorption. Osteoclast are cells that disintegrate the bone to start normal bone remodelling and also contemplate bone loss in pathologic condition by growing its resorptive capacity.
