Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which proteins give structure to skin, tendons, and ligaments?
A
collagen & elastin
B
activation energy
C
nucleotides and lipids
D
water and hemoglobin
Explanation: 

Detailed explanation-1: -Collagen is the most abundant protein in your body. It accounts for about 30% of its total protein. Collagen is the primary building block of your body’s skin, muscles, bones, tendons and ligaments and other connective tissues.

Detailed explanation-2: -Collagen is protein molecules made up of amino acids. It provides structural support to the extracellular space of connective tissues. Due to its rigidity and resistance to stretching, it is the perfect matrix for skin, tendons, bones, and ligaments.

Detailed explanation-3: -Collagen I-found in bones, tendons, organs. Collagen III-found mainly in reticular fibres ( fine fibrous connective tissue occurring in networks to make up the supporting tissue of many organs).

Detailed explanation-4: -Collagen is the most abundant protein in animals. This fibrous, structural protein comprises a right-handed bundle of three parallel, left-handed polyproline II-type helices. Much progress has been made in elucidating the structure of collagen triple helices and the physicochemical basis for their stability.

Detailed explanation-5: -Collagen proteins are the building blocks of connective tissues like tendons, ligaments, and muscles. The strong structures that collagen proteins are able to create are what make up most of the foundational and structural parts of your body.
