#Unit 1. Molecules and their Interaction Relevant to Biology
  1. There are two kind of pyruvate kinase 1. Liver isozyme (L form), 2. Muscle isozyme (M form)
  2. The liver isozyme (L form) is also regulated hormonally by glucagon. Glucagon to PKA mediated phosphorylation inactivate Pyruvate Kinase L.
  3. The muscle isozyme (M form) PK is not affected by this phosphorylation mechanism.
  4. Glucagon increases the cellular level of fructose 2,6 bisphosphate, stimulating glycolysis and inhibiting gluconeogenesis.
