Which protein is most directly responsible for providing tensile strength to skin, tendons, and bone matrix?

Hemoglobin, which is a transport protein that has no direct structural role in connective tissue

Myosin, a motor protein that primarily generates sliding motion between filaments rather than providing extracellular tensile strength

Amylase, an enzyme that digests starch and is unrelated to connective tissue structure

Collagen, the major fibrous structural protein that forms cross-linked fibers providing tensile strength to connective tissues
