Questions & Step-by-Step Solutions

Which electrolyte is most important for muscle contraction?
  • Step 1: Understand that muscles need signals to contract.
  • Step 2: Know that electrolytes are minerals in the body that help with these signals.
  • Step 3: Identify that calcium is one of these important electrolytes.
  • Step 4: Learn that when a muscle is signaled to contract, calcium is released inside the muscle cells.
  • Step 5: Recognize that calcium interacts with proteins in the muscle cells to allow the muscle to shorten and contract.
  • Step 6: Conclude that without calcium, muscles cannot contract properly.
