Cellular mechanisms

Cellular mechanisms refer to the processes and activities that occur within cells to maintain life and function. These mechanisms include how cells communicate, obtain energy, grow, and replicate. For example, cells use enzymes to speed up chemical reactions, transport molecules in and out through their membranes, and respond to signals from their environment. Each mechanism is essential for the overall operation of organisms, allowing for everything from healing and immunity to reproduction and development. Understanding these processes helps us grasp how life functions at the most fundamental level.
