- - - - this product is then the substrate for the next enzyme and so on……
        
        These pathways occur as a result of many regulated steps.
        
        During each step in a metabolic pathway some chemical energy is transformed into heat, which can be used
        to maintain stable body temperatures in many organisms, including humans.
        
        In a metabolic pathway there are;
        
        Many regulated steps
        
        Each step loses some energy as heat
        
        Some steps produce intermediate compounds
        
        Specific enzymes are required at each step
  - - - Aerobic respiration is a good example of this.
    - - Photosynthesis in plants is a good example.
  - - - contraction of muscle cells
      - the movement of chromosomes during mitosis
    - - active transport of molecules against the concentration gradient
    - - synthesising critical macromolecules
      - such as proteins and nucleic acids.
    - - Cells maintain this work by energy coupling.
      - Metabolic reactions link energy releasing pathways to those that require energy with the immediate source of energy to drive the work being provided by molecules of ATP
      - Two of the most important metabolic pathways that have already been studied are photosynthesis and aerobic respiration
- - - - Internal system of membranous flattened sacs called thylakoids.
      - Photosynthetic pigments such as chlorophyll are contained within the thylakoid membranes.
      - First stage of photosynthesis the pigments are able to trap light energy, therefore important role in the conversion of light energy into chemical energy.
    - - Inner membrane folded to form cristae that increase SA:V for attachment of ATP synthase, important for aerobic respiration.
