From the Guidelines
Cellular physiology is the study of how cells function at the molecular and biochemical level, examining processes such as metabolism, energy production, protein synthesis, cell signaling, transport mechanisms, and cell division to understand how cells maintain life and respond to their environment. This field is crucial for understanding how tissues, organs, and entire organisms function, as disruptions in cellular processes often lead to disease states. The study of cellular physiology integrates concepts from biochemistry, molecular biology, and biophysics to provide a comprehensive understanding of how cells work as the basic units of life 1.
Some key aspects of cellular physiology include:
- Metabolism: the energy-providing processes of the cell, which can be either normal (eumetabolism) or abnormal (dysmetabolism) 1
- Cell signaling: the processes by which cells communicate with each other and respond to their environment
- Transport mechanisms: the processes by which cells move molecules and ions across their membranes
- Cell division: the process by which cells reproduce themselves
Understanding cellular physiology is essential for developing treatments that target specific cellular dysfunctions, and it has significant implications for our understanding of disease states and the development of novel therapeutic approaches 1.
In the context of cell death, cellular physiology plays a critical role in understanding the various processes that occur within cells to maintain life, and how disruptions in these processes can lead to cell death 1. The study of cellular physiology can provide valuable insights into the mechanisms of cell death and the development of therapeutic strategies to prevent or modulate cell death.
Overall, the study of cellular physiology is essential for understanding how cells function and respond to their environment, and it has significant implications for our understanding of disease states and the development of novel therapeutic approaches.

Definition of Cellular Physiology
Cellular physiology refers to the study of the functions and processes that occur within cells, including the regulation of metabolic pathways, signaling mechanisms, and mechanical properties.
Key Aspects of Cellular Physiology
- Metabolism: Metabolism plays a fundamental role in biology, impacting all cellular functions 2. It involves the regulation of metabolic pathways, which can be influenced by various factors, including the availability of metabolites and the activity of enzymes.
- Signaling Mechanisms: Signaling pathways and cross-talk among them are crucial for cellular processes, including proliferation, apoptosis, and differentiation 3.
- Mechanical Properties: Cells generate and sustain mechanical forces within their environment as part of their normal physiology, and changes to cell mechanical properties can result in various pathologies 4.
- Cell-ECM Adhesion: Cell-ECM adhesion can initiate intracellular signaling that changes an array of fundamental cell functions, including metabolism and migration 5.
- Regulation of Metabolic Reactions: Metabolic reactions are catalyzed by proteins, and the regulation of these reactions is essential for maintaining metabolic homeostasis, which can be achieved through various mechanisms, including phase separation of enzymes 6.
Importance of Cellular Physiology
Understanding cellular physiology is essential for understanding the mechanisms of various diseases, including cancer, metabolic syndrome, and aging. It can also provide insights into the development of potential therapeutic interventions.
