Question

Quizplus · Accepted Answer

Structural proteins such as collagen and keratin provide support and strength to tissues and organs. They are found in muscles, bones, and other connective tissues, but not in blood or hormones which serve other functions in the body. Structural proteins provide physical support and shape to cells and tissues. Muscles, bones, and other connective tissues such as tendons and cartilage require structural proteins like collagen and elastin for their structural integrity. Blood does not require structural proteins as its primary function is to transport oxygen, nutrients and waste products. Hormones are signaling molecules that regulate various physiological functions and do not have a structural role.
