[Campbell Biology P.1183] Which of the following statements accurately describes the contrast... | Practice Question

Which of the following statements accurately describes the contrasting roles of osteoblasts and osteoclasts in the mammalian skeleton?

  • A: Osteoblasts secrete bone matrix and build bone, while osteoclasts resorb bone components and remodel the skeleton.
  • B: Both osteoblasts and osteoclasts are responsible for secreting bone matrix.
  • C: Osteoclasts build new bone, and osteoblasts break down old bone.
  • D: Neither osteoblasts nor osteoclasts play a role in bone remodeling.

Explanation

The text states, "Cells called osteoblasts secrete bone matrix and thereby build and repair bone... Osteoclasts have an opposite function, resorbing bone components in remodeling of the skeleton."
