In cells, the enzyme-catalyzed reactions that extract chemical energy from nutrient molecules and use it to synthesize and assemble cell components
Metabolism is a highly coordinated cellular activity aimed at achieving the following goals:
- Obtain chemical energy.
- Convert nutrient molecules into the cell’s own characteristic molecules.
- Degrade biomolecules
Metabolism, the sum of all the chemical transformations taking place in a cell or an organism, occurs through a series of enzyme-catalyzed reactions that constitute metabolic pathways.
