1. Skeletal muscle used ATP to contract. Then, ATP is broken down into ADP and P, which release energy.
2. A) The sarcoplasmic reticulum is the organelle that stores calcium in muscles cells.
B) In order for calcium to be released from this organelle some events must occur. First, an action potential needs to reach the synaptic terminal. Then acetylcholine needs to be released into the sarcoplasm. After that, ACH molecules will land on receptors that are on the motor end plate. Then, an action potation is made and travels across the sarcolemma surface. After, the action potential travels down T Tubules. Lastly, calcium ions are released into the sarcoplasm.
