Question

what occurs during bone remodeling?
removal of existing bone by osteocytes and the deposition of new bone by osteogenic cells
removal of existing bone by osteoclasts and the deposition of new bone by osteogenic cells
removal of existing bone by osteoblasts and the deposition of new bone by osteoclasts
removal of existing bone by osteoclasts and the deposition of new bone by osteoblasts

Explanation:

Bone remodeling is a continuous process. Osteoclasts are responsible for bone resorption (removing existing bone). Osteoblasts are in charge of bone formation (depositing new bone). Osteocytes are mature bone cells that maintain bone matrix. Osteogenic cells are stem - like cells that can differentiate into osteoblasts.

Answer:

removal of existing bone by osteoclasts and the deposition of new bone by osteoblasts
