Correct answer: C. Tendons
- A. Muscle
- B. Red blood cells
- C. Tendons
- D. Blood Plasma
Explanation
Collagen proteins are present in tendons throughout the body.Collagen is a fibrous protein that is a major component of the extracellular matrix in various connective tissues throughout the body. Tendons are strong, flexible bands of connective tissue that attach muscles to bones, providing stability and transmitting the force generated by muscles to bones to move. Collagen fibers are abundant in tendons, providing tensile strength and resilience to withstand the forces exerted during muscle contraction and movement. Therefore, collagen proteins are predominantly found in tendons among the options listed, although they are also present in other connective tissues such as ligaments, skin, cartilage, and bones.

About Macromolecules
Proteins are classified by shape, composition and structure, from primary amino acid sequence to secondary, tertiary and quaternary organisation, and their biological roles are linked to this structure. Enzymes are examined as protein biocatalysts, including active sites, substrate specificity, activation energy, cofactors and factors affecting activity.
