Differences between Catabolism and Anabolism

Anabolism	Catabolism
1.    It is a constructive process of metabolism	It is a destructive process of metabolism
2.    In anabolism, complex molecules (e.g. proteins) are synthesized from simple molecules (Amino acids)	In catabolism, complex molecules (e.g. Glycogen) are broken down into simple molecules (glucose)
3.    It is an energy (ATP) requiring process	It is an energy (ATP) releasing process
4.    It is a “Up-hill” process	It is a “Down-hill” process
5.    E.g. Protein synthesis, Glycogen synthesis, Photosynthesis	E.g. Glycogenolysis, Glycolysis, Digestion, cellular respiration
