• Metabolism

  A series of chemical reactions in the body that converts food into energy
• Types of metabolism


  • Catabolism
  • Anabolism
• Catabolism


  The set of metabolic pathways that breaks down molecules into smaller units that are either oxidized to release energy or used in other anabolic reactions
• Anabolism


  The set of metabolic pathways that construct molecules from smaller units, these reactions require energy, known also as an endergonic process
• Differences between catabolism and anabolism

  • Molecules
  • Smaller units
  • Energy
• CATABOLISM EXAMPLES


  • Breakdown of polysaccharides into monosaccharides to generate energy
  • Breakdown of nucleic acids into nucleotides for transmitting genetic information
  • Breakdown of proteins into amino acids, either to make new ones or to produce glucose in the blood
  • Breakdown of food in the stomach for the nutrients to absorbed into the blood vessels
• Plant cells have rigid cell walls that give them their shape and support structure.
