Final answer:
Amino acids are used to make transport proteins, vital for moving substances around the body and across cell membranes, including hemoglobin for oxygen transport and carrier proteins for molecules like amino acids and glucose.
Step-by-step explanation:
Amino acids are used to make transport proteins, which play a crucial role in moving substances into, out of, and around the body, as well as across cell membranes. Transport proteins, such as hemoglobin, are essential for transporting oxygen to various organs and tissues. They can function as channels or carriers within cellular membranes, ensuring that molecules such as amino acids, glucose, and oxygen can safely and efficiently reach their destinations.
Examples of transport proteins include hemoglobin, which carries oxygen in the blood, and carrier proteins which can bind to substances and change their shape to move molecules across the membrane. Integral proteins and peripheral proteins located in cell membranes also have important transport roles. These proteins ensure proper cellular function and overall physiological processes.
