Cellular processes

Definition

Cellular processes refer to the series of biochemical reactions and physiological activities that occur within a cell to maintain its life and function. These processes include essential functions like metabolism, signal transduction, and cellular communication, which are crucial for the cell's ability to respond to its environment and maintain homeostasis. Understanding cellular processes is key to exploring how advanced technologies can enhance imaging and diagnostics in biological systems.
