Cellular regulation refers to the processes that control the activities and functions of cells. This includes the regulation of gene expression, cell growth, division, and response to external signals. By managing these processes, cells can adapt to changes in their environment and maintain homeostasis, which is essential for the overall health of an organism. Key components of cellular regulation include proteins, enzymes, and hormones. These molecules interact with cellular pathways to influence various functions, such as metabolism and cell signaling. Proper cellular regulation is crucial for preventing diseases, including cancer, where regulation mechanisms may become disrupted.
