Edexcel IGCSE Biology: Double Science 复习笔记 2.6.1 Energy

ATP

 

  • Organisms need energy for things such as:
    • Chemical reactions to build larger molecules from smaller molecules
    • Muscle contraction to allow movement
    • Keeping warm (to maintain a constant temperature suitable for enzyme activity)

     

  • Cellular respiration is an exothermic reaction that is continuously occurring in living cells
  • The chemical process of cellular respiration releases energy from glucose
  • The energy is transferred via the molecule Adenosine Triphosphate (ATP)
  • ATP, produced in respiration in the mitochondria, is required for living processes to occur within cells and organisms
