03 · How Cells Use Energy, Move Substances, and Communicate
Cells exchange substances, use energy, and respond to their surroundings. These activities are linked: energy maintains ion differences across membranes, and those differences can help transport nutrients and support electrical signaling. Understanding the connection prepares us to study nerves, muscles, digestion, and metabolism.
