Need answer to be as short and simple as possible please.
1. Describe the three type of energy metabolism (ATP production) in skeletal muscle (how each occurs, the advantages of each, and when each is used):
- Phosphagen systems
-Anaerobic glycolysis & Fermentation
- Aerobic respiration
2. Describe the steps of contraction in skeletal muscle, starting with release of ACh from the synaptic end bulb and ending with muscle relaxation (include the steps of the Sliding Filament Theory of Contraction).
3. Describe the events that occur during an action potential; understand the roles of:
- Na+
- K+
- Ligand-gated Na+ gates
- Voltage-gated Na+ gates
- Voltage-gated K+ gates
4. Explain how the contraction process is controlled for smooth muscle; how is smooth muscle innervated? How are single and multi-unit smooth muscle systems different?
5. Compare and contrast graded potentials and action potentials.
