Which of the following are intracellular events occurring in fibroblast during synthesis of collagen:
**Core Concept**
The synthesis of collagen involves a series of intracellular and extracellular events. Intracellular events include transcription of collagen genes, translation of mRNA into polypeptide chains, and post-translational modifications such as hydroxylation and glycosylation.
**Why the Correct Answer is Right**
The correct answer involves the process of collagen synthesis within fibroblasts, which includes hydroxylation of proline and lysine residues by **prolyl hydroxylase** and **lysyl hydroxylase**, glycosylation, and formation of triple helix structure. These steps are crucial for the stability and function of collagen.
**Why Each Wrong Option is Incorrect**
**Option A:** Incorrect as it's not specified,
**Option B:** Incorrect as it's not provided,
**Option C:** Incorrect because it's missing,
**Option D:** Incorrect since the option is not given.
**Clinical Pearl / High-Yield Fact**
Collagen synthesis defects can lead to diseases like **Ehlers-Danlos syndrome** and **osteogenesis imperfecta**. Understanding the intracellular events in collagen synthesis is crucial for diagnosing and managing these conditions.
**Correct Answer:** Not provided in the query.
