Which protein provides a structural framework in connective tissue?

Explanation:
Collagen provides the structural framework in connective tissue. It forms long, triple-helix molecules that assemble into strong fibers, creating the extracellular matrix that gives tissues their tensile strength and shape. This scaffold supports skin, bone, cartilage, tendons, and ligaments, and it helps organize other matrix components. Elastin, on the other hand, gives tissues the ability to stretch and recoil; actin is a cytoskeletal and contractile protein involved in cell movement and muscle contraction; myosin works with actin to power muscle contraction. The robust, organized network formed by collagen is what furnishes connective tissue with its durable structural framework.
