Cellular metabolism comprises all chemical reactions within cells that enable them to maintain life, grow, reproduce, and respond to their environments. It is divided into catabolic pathways that break down molecules to release energy and anabolic pathways that build complex molecules from simpler ones.

Cellular Metabolism

Cellular metabolism

Chemical reactions involve the transformation of substances through the breaking and forming of chemical bonds, resulting in the conversion of reactants into products. These reactions are governed by the principles of thermodynamics and kinetics, which dictate the feasibility and rate of these transformations.

Respond to environments

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.

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.
