2. Calcium activates phosphorylase
kinase - the first protein kinase discovered
by Fischer and Krebs. 3. Phosphorylase kinase
phosphorylates phosphorylase, which is activated
4. Glycogen is broken to glucose. This is used
to generate ATP 5. The muscle works and requires
energy in the form of ATP 6. The muscle contains
muscle cells
7. Contractile proteins in the
muscle are activated by calcium
