Question

When at rest,the NMDA receptor is blocked by ________ ions.​

Quizplus · Accepted Answer

The NMDA receptor is blocked by magnesium ions when at rest. This blockage is necessary to prevent the influx of calcium ions into the cell, which could result in excitotoxicity and cell death. When the appropriate neurotransmitter binds to the receptor, the blockage is lifted and calcium ions are allowed to flow into the cell.
