  • Plants need energy for things like photosynthesis, active transport, DNA replication, cell division and protein synthesis.
  • Metabolic pathway - A series of small reactions controlled by enzymes e.g. respiration and photosynthesis.
  • Phosphorylation - Adding phosphate to a molecule.
  • Photophosphrylation - Adding phosphate ro a molecule using light.
  • Photolysis - The splitting of a molecule using light energy.
  • Hydrolysis - The splitting of a molecule using water.
  • Decarboxylation - The removal of carbon dioxide from a molecule.
  • Dehydrogenation - The removal of hydrogen from a molecule.
  • Redox Reactions - Reactions that involve oxidation and reduction.
  • If something is reduced it has gained electrons and may have gained hydrogen or lost oxygen.
  • If something is oxidised it has lost electrons, and may have lost hydorgen or gained oxygen.
  • A conenzyme is a molecule that aids the function of an enzyme. The usually work by transferring a chemical group from one molecule to another.
  • A coenzyme used to photosynthesis is NADP which transfers hydrogen from one molecule to another this means it can preform redox reactions.
