In Unit 4, students continue to learn about the role of cells, focusing on how cells use energy and information transmission to communicate and replicate. Through systems of complex transduction pathways, cells can communicate with one another.
AP Biology Unit 4 – Cell Communication and Cell Cycle. Cell communication and the cell cycle are fundamental processes that govern cellular behavior and reproduction. Signaling molecules trigger responses by binding to receptors, initiating signal transduction pathways that amplify and transmit information within cells.
