Question: Which statements best compare a function of proteins and lipids in a human cell?
Proteins and lipids both play important roles in human cells, but their functions differ significantly. Proteins are involved in a wide range of cellular functions, including enzyme catalysis, cell signaling, and structural support. They are composed of long chains of amino acids and have complex three-dimensional structures that enable them to carry out specific functions within the cell. Lipids, on the other hand, are primarily involved in energy storage and membrane structure. They are composed of fatty acids and glycerol and form the main structural component of cell membranes, which regulate the transport of materials into and out of the cell. While both proteins and lipids are essential for the proper functioning of human cells, their distinct structures and functions enable them to perform different roles within the cell.
