Expert Solution

Answer:

What is the cell type that produces osteocalcin and collagen?

Osteocalcin

Osteocalcin is a low molecular weight hydroxyapatite-binding protein and is involved in bone remodeling process.
Osteocalcin is regarded as a marker for bone formation
Osteocalcin is produced by Osteoblast during bone matrix formation.
Osteblasts are bone forming cells that are produced from the mesenchymal osteoprogenitor cells.

Collagen:

Collagen is extracellular fibrous that plays an important role in organizing extracellular matrix. It is composed of a triple helix of alpha chains of amino acids and is the main constituent of the connective tissue.
Collagen is produced by Fibroblast cells.
Fibroblast cells are involved in the synthesis of extracellular matrix and collagen and are a important contributor to the wound healing process and cell maintenance.
Fibroblast cells are mature differentiated cells which are usually spindle-shaped with an oval flat nucleus.

List the steps in the synthesis of type I collagen, starting with the mRNA and ending with the cross-linked extracellular fibril. For each step that you list, state whether that step is typical for most secreted proteins, or whether that step is specific to collagens. I know the steps but I don't know which ones are for most proteins and which one are only for collagen.

Osteogenesis imperfecta is a disease caused by a mutation in collagen (type X), which causes the infected individual to have brittle bones that easily fracture. Collagen typically has a triple helical structure consisting of three intertwined polypeptide chains (as shown below) with each polypeptide chain having a glycine every third amino acid. While Osteogenesis imperfecta can be caused by a variety of mutations, a single amino acid change is sufficient to cause certain forms of the disease. If the mutation...
