Final answer:
Calcium is the electrolyte that stimulates muscle cells to contract due to its role in the process of muscle contraction.
Explanation:
Calcium is the electrolyte that stimulates muscle cells to contract. It plays a crucial role in the process of muscle contraction by binding to troponin, allowing the myosin and actin filaments to interact and generate force.
When a muscle cell is depolarized, calcium is released from the sarcoplasmic reticulum, leading to the contraction of the muscle fiber. This process highlights the importance of calcium in muscle function.
