As an action potential reaches a muscle cell, it triggers calcium to release from the sarcoplasmic reticulum of the cells. The calcium ions then flow into the cytoplasm and bind to the troponin and tropomyosin molecules in the actin filaments of the muscle cells. The binding of calcium allows the troponin to change shape and expose the actin-myosin binding site.
Best Answer: Calcium flows through t-tubules. In response to stimulation, calcium channels in t-tubules open and allow calcium to flow down it's electro-chemical gradient into the cell. In skeletal muslce it contributes greatly to muscle contraction. The purpose of t-tubules is to allow depolarization to quickly penetrate to the interior of the cell. The t-tubules help to bring the extracellular environment to all parts of the muscle cell more quickly which better coordinates muscle contraction.
