Respiration of Different Respiratory Substrates

Other Respiratory Substrates

As well as sugars, other substances can be broken down within cells to release energy.

  • Lipids can be hydrolysed to glycerol and fatty acid chains. The glycerol is then converted into triose phosphate and the fatty acid chains are broken into small fragments which are then converted into acetyl coenzyme A.
  • Proteins can be hydrolysed into the constituent amino acids. The amino acids are deaminated and then used at different points in respiration depending on the number of carbon atoms within them.
