Question

Match the following terms below A-E to the descriptions: A) Calcium ions B) Anaerobic pathway C) Sodium ions D) Aerobic pathway E) Acetylcholine The final chemical messenger and "trigger" for muscle contraction. It binds to troponin. A neurotransmitter released at motor end plates by the axon terminals. It diffuses across the cell membrane resulting in depolarization. Pathway utilized in marathons (long distance low intensity energy utilization). 25 meter swim (short distance and high intensity energy utilization).
