Metabolic pathways of respiration – making ATP

The main substrate within the respiration pathway is glucose.

The metabolic pathway involved in respiration can be split into three main parts:

  1. Glycolysis - occurs in the cytoplasm.
  2. Citric acid cycle - occurs in the matrix of the mitochondria.
  3. Electron transport chain - occurs in the inner membrane of the mitochondria.
