Cellular regulation refers to the processes that control and coordinate the activities of cells, ensuring they function properly. This includes the regulation of gene expression, protein synthesis, and cell signaling pathways. By managing these activities, cells can respond to changes in their environment and maintain homeostasis. Key components of cellular regulation include enzymes, hormones, and receptors. Enzymes facilitate biochemical reactions, while hormones act as signaling molecules that communicate between cells. Receptors on cell surfaces detect these signals, triggering responses that help the cell adapt to various conditions, such as growth, division, or stress.
