Final answer:
Lipids interact in carrying out cellular processes by serving multiple functions, such as energy storage, protein transport, and signaling. The structure of lipids, particularly phospholipids, is important for cell membrane composition and fluidity.
Step-by-step explanation:
Lipids serve multiple functions in cellular processes. They are involved in the storage of energy, as carriers for transporting proteins across the membrane, and as signaling molecules.
Lipids can also serve as structural components of hormones. The structure of lipids, such as phospholipids, plays a crucial role in the composition and fluidity of cell membranes. Lipids are a diverse group of molecules that play important roles in various cellular processes.
