Question

Collagen present in skin is:

• A. Type II
• B. Type I
• C. Type III
• D. Type IV

Answer 1

The Correct Option is B

Collagen is an essential protein in the human body, providing structural support and playing a critical role in skin, bone, and connective tissues. Different types of collagen are distributed throughout the body, each serving specific functions. Here's a breakdown of the relevant types:

• Type I Collagen: This is the most prevalent form of collagen, found predominantly in skin, bones, tendons, and ligaments. It provides tensile strength and is integral to the structural organization of the skin.
• Type II Collagen: Primarily found in cartilage, this type is crucial for joint health and function.
• Type III Collagen: Often found alongside Type I, it is present in skin, muscles, and blood vessels. It contributes to the elastic quality of tissues.
• Type IV Collagen: Found in the basal lamina, it is a part of the basement membrane that supports layers of cells, crucial for filtration and structural integrity in epithelial tissues.

Given these roles, Type I Collagen is the primary collagen present in the skin, providing strength and resilience. Therefore, the correct answer is:

Type I
