Question
Which of the following is associated with osteoclast reabsorption of bone?Multiple ChoiceHydrogen ions form an acid environment in bone matrix.Blood calcium is decreased.Ca2+ is actively transported from blood to bone matrix.Osteoblasts form collagen and proteoglycans.The protein components of bone matrix are synthesized.
Solution
The process associated with osteoclast reabsorption of bone is "Hydrogen ions form an acid environment in bone matrix."
Here's a step-by-step explanation:
-
Osteoclasts are cells that break down bone tissue. This process is known as bone resorption.
-
During bone resorption, osteoclasts attach to the bone matrix. They then secrete hydrogen ions (H+) into the space between the osteoclast and the bone surface.
-
These hydrogen ions combine with water to form a weak acid, which helps to dissolve the mineral component of the bone matrix.
-
This creates an acidic environment that aids in the breakdown of the bone matrix, allowing the osteoclasts to absorb the bone tissue.
So, the statement "Hydrogen ions form an acid environment in bone matrix" is associated with osteoclast reabsorption of bone.
