All cells regulate gene expression in response to changes in the external environment. For unicellular organisms, specific mechanisms have evolved to allow these cells to metabolize various fuels based on their availability in the external milieu. In part, these mechanisms involve conditional transcription of genes encoding enzymes unique to specific metabolic pathways in the presence of appropriate nutrients. The study of such control mechanisms has led to several of the classic paradigms for transcriptional regulation present in today's textbooks.
