Why do nerves spend more ATP the more impulse is transmitted, if ATP is spent when nerve is in resting state(polarization)?
In: Biology
You can think of precompiled as a row of Dominos falling over, and after each pulse u have to put them upright again and that costs atp.
Nerve Cells maintain a difference of charge between their inside and outside.
They achieve this by pumping ions around and that uses atp.
A nerve pulse opens different channels for the ions to flow through to equalize the charge difference. Afterwards the pumps have to work to make it ready for the next pulse.
