a. it is found i. n a tissue
b. it is made up of amino acids
c. it is made up of twisted chains
d. it stores energy

Hello!

The answer is B. It is made up of amino acids.

Explanation:

Collagen:

Collagen is the most abundant protein found in mammals and makes up 25%of the entire protein count. Collagen is mostly present in the form of collagen fibers which give the extracellular matrix structure and support.

Amino acids:

Amino acids are organic molecules that possess the amino (-NH2) functional group. Amino acids are the building block of proteins. They combine together through peptide linkages to form polypeptides and polypeptides link together in the form of complex proteins.

Collagen possesses a complex structure of amino acids arranged in three alpha-chains wound around each other to give a triple-helix.
