Step 1I'll solve this problem by listing the six steps of the sliding filament theory with clear explanations:
Step 2: Calcium Release
When a muscle cell receives a nerve signal, calcium ions ($$Ca^{2+}$$) are released from the sarcoplasmic reticulum into the muscle cell's cytoplasm.
These calcium ions are crucial for initiating muscle contraction.
Final Answer
The six steps of the sliding filament theory are: (1) Calcium Release, (2) Calcium Binding to Troponin, (3) Myosin Binding Sites Exposed, (4) Cross-Bridge Formation, (5) Myosin Head Pivoting, and (6) ATP-Powered Detachment and Reset.
