Cellular processes

Definition

Cellular processes refer to the biochemical and physiological activities that occur within cells to maintain life, including metabolism, communication, growth, and division. These processes are essential for the functioning of all living organisms and are often modeled mathematically to understand their dynamics and interactions within biological systems.

5 Must Know Facts For Your Next Test

1. Cellular processes are governed by a series of complex networks involving enzymes, proteins, and nucleic acids that regulate metabolic pathways.
2. Mathematical models can simulate cellular processes, providing insights into how cells respond to various stimuli and environmental changes.
3. Key cellular processes include glycolysis, Krebs cycle, protein synthesis, and apoptosis, each playing critical roles in cell function and survival.
4. These processes are interconnected; for instance, energy produced during metabolism is vital for cellular signaling and growth.
5. Disruptions in normal cellular processes can lead to diseases such as cancer, where uncontrolled cell division occurs due to failures in regulatory mechanisms.
