Cellular homeostasis refers to the maintenance of stable and balanced internal conditions within a cell, despite external changes in the environment. This includes the regulation of various cellular processes such as nutrient uptake, waste elimination, pH balance, and energy production. Disruption of cellular homeostasis can lead to various health conditions and diseases, making it a crucial area of study in cell biology and physiology. Researchers in this field aim to understand the mechanisms involved in maintaining cellular homeostasis and develop strategies to target these processes for therapeutic purposes.
