Question

Quizplus · Accepted Answer

Calcium ions are widely important in intracellular signaling, as they play a key role in activating enzymes and triggering cellular responses. In contrast, sodium and potassium ions are primarily involved in maintaining membrane potential, while chloride ions are important for balancing electrolyte concentrations. Cobalt ions are not generally involved in intracellular signaling.
