metabolic pathways

• metabolism - all chemical reactions that occur within a cell
• metabolic enzymes - enhances and regulates Metabolic reaction
• metabolite - is any molecule, either a nutrient, an

  intermediary product, or an end product, in a metabolic reaction.
• METABOLIC PATHWAYS -Series of linked biochemical

  reactions that occur in a stepwise manner, from a starting material to end product.
• CATABOLISM - organic nutrient molecules are converted into smaller, simpler end products
• ANABOLISM - small, simple molecules are built up into large and more complex molecules.
• Catabolic reactions - involve the breaking of

  bonds; whenever chemical bonds are

  broken, energy is released
• Anabolic reactions - involve the creation of

  bonds, which require energy
