1. How are mitochondria adapted for respiration ?

  • Folded inner membrane, increasing surface area. Lots of ATP synthase for ATP production. Matrix contains all the reactants for the Krebs cycle to take place.
  • Lots of ATP synthase for lots of ATP synthesis. Folded inner membrane increasing surface area. Lack of reactants in the matrix to stop the Krebs cycle from over production.
  • A lack of ATP to ensure there is not too much ATP production. All reactions are in the crista.
  • Mitochondria have extra membranes within the crista for extra surface area
