Cellular Metabolism encompasses the entire spectrum of intricate biochemical reactions occurring within a cell necessary for sustaining life, including energy conversion and biosynthesis. It represents the dynamic equilibrium between processes that build up (anabolism) and break down (catabolism) molecular substrates. Understanding this cellular economy is central to assessing overall physiological vitality.
Origin
The term originates from the Greek word ‘metabole,’ meaning change or conversion, applied specifically to the transformations that sustain living matter at the fundamental cellular level.
Mechanism
Metabolism functions through tightly regulated pathways where nutrient substrates are processed to generate Adenosine Triphosphate (ATP), the cell’s energy currency. Hormones such as insulin dictate substrate utilization by promoting glucose uptake, while thyroid hormones directly influence the expression of metabolic enzymes, thereby setting the overall basal rate of cellular activity.
