Metabolism Consists of all of the chemical reactions that take place in a cell Organized into metabolic pathways Each contains a series of steps Specific enzymes speed up each step of the pathway

OXIDATION & REDUCTION REACTIONS Metabolism is broken down into two parts: Catabolism – molecules are broken down through metabolic processes to release the energy stored in eir chemical bonds. their chemical bonds. Anabolism – metabolic processes in which the energy derived from catabolism is used to build large organic molecules from smaller ones.
