Detailed explanation-1: -The major functions of proteins are providing structure, regulating body processes, transporting materials, balancing fluids, helping with immunity, and providing energy.
Detailed explanation-2: -Proteins have multiple functions, including: acting as enzymes and hormones, maintaining proper fluid and acid-base balance, providing nutrient transport, making antibodies, enabling wound healing and tissue regeneration, and providing energy when carbohydrate and fat intake is inadequate.
Detailed explanation-3: -Protein helps repair and build your body’s tissues. It drives metabolic reactions, maintains pH and fluid balance, and keeps the immune system strong. It also transports and stores nutrients and can act as an energy source.
Detailed explanation-4: -Membrane proteins mediate processes that are fundamental for the flourishing of biological cells. Membrane-embedded transporters move ions and larger solutes across membranes, receptors mediate communication between the cell and its environment and membrane-embedded enzymes catalyze chemical reactions.
