Intermediary metabolism refers to the complex network of biochemical reactions that occur within cells, encompassing both anabolic and catabolic pathways that transform nutrients into energy and building blocks for cellular function. It is crucial for maintaining cellular homeostasis, energy balance, and the synthesis of essential biomolecules.

Intermediary Metabolism

Biochemical reactions are fundamental processes that occur within living organisms to sustain life, involving the transformation of molecules through enzyme-catalyzed reactions. These reactions are crucial for metabolism, energy production, and the synthesis of essential biomolecules, operating under specific conditions of temperature, pH, and concentration to maintain homeostasis.

Biochemical Reactions

Anabolic pathways are a series of biochemical reactions that construct molecules from smaller units, requiring energy input, typically in the form of ATP. These pathways are essential for cell growth, repair, and differentiation, playing a crucial role in processes like protein synthesis and DNA replication.

Anabolic Pathways

Catabolic pathways are metabolic processes that break down molecules into smaller units, releasing energy that is used by the cell. These pathways are crucial for maintaining cellular energy balance and providing the building blocks for anabolic reactions.

Catabolic Pathways

Transformation of nutrients

Energy balance is the state where the calories consumed through food and drink are equal to the calories expended through basal metabolic rate and physical activity. Achieving energy balance is crucial for maintaining a stable body weight and overall health.

Energy Balance

Cellular function encompasses the myriad activities carried out by cells to maintain homeostasis, facilitate growth, and ensure survival. It involves complex interactions between cellular structures and biochemical pathways to perform tasks such as energy production, molecular transport, and signal transduction.

Cellular Function

Cellular homeostasis refers to the processes by which cells maintain a stable internal environment, crucial for optimal function and survival. It involves a dynamic balance of inputs and outputs, regulating factors such as pH, ion concentration, and nutrient levels to adapt to changes both inside and outside the cell.
