The correct answer encompasses the variety of functional roles that proteins play in biological systems. Proteins are essential macromolecules that perform a wide array of functions crucial for life.

Transport proteins facilitate the movement of substances across cell membranes and throughout the body, such as hemoglobin transporting oxygen. Structural proteins provide support and shape to cells and tissues; examples include collagen in connective tissues and keratin in hair and nails. Enzymes, which act as catalysts, increase the rate of biochemical reactions without being consumed in the process, playing a vital role in metabolic pathways. Defense proteins, such as antibodies, help to protect the body from pathogens. Hormones function as signaling molecules that regulate physiological processes, and receptor proteins are involved in communication between cells by binding to specific molecules, leading to a response in the target cell.

Thus, all the options listed represent important categories of protein functions, confirming that the comprehensive answer encompasses the complexity of protein roles in the body.
