Three-quarters of the substantial amount of energy consumed by the brain is used to run a single molecular machine that maintains the resting potential of neurons.What is this machine called? A)K⁺ leak channel B)sodium-potassium pump C)acetylcholine receptor D)voltage-gated sodium channel E)voltage-gated calcium channel

Question

Quizplus · Accepted Answer

The sodium-potassium pump is responsible for maintaining the resting potential of neurons by actively transporting sodium ions out of the cell and potassium ions into the cell. This process requires a significant amount of energy, accounting for three-quarters of the energy consumed by the brain.
