Answer:
Part of the extracellular matrix secreted by osteocytes. (Ans. B)
Explanation:
Cells which are present on bones are known as osteocytes. Bone is composed of extracellular matrix, and cells. There are three types of cells which are present in the bones:
1) Osteoprogenitor cells.
2) Osteoblast.
3) Osteocyte.
Extracellular matrix is composed of organic matrix consisting glycoproteins, proteoglycans, osteocalcin also known as calcium binding proteins, and osteonectin which anchors bone mineral to collagen.
The are opposite processes. Photosynthesis requires carbon dioxide, water and sunlight to create oxygen and glucose. Where cellular respiration requires oxygen and glucose to create ATP energy, and carbon dioxide and water as waste products. Since the processes are opposite of each other they are in a never ending cycle. One provides the other with the necessary reactants to create the products
