Respuesta :
The answer is potassium channels.
The rapid leaf movements resulting from a response to touch (thigmotropism) primarily involve potassium channels.
What is potassium channel?
Almost all living things contain potassium channels, which are the most common form of ion channel. They build holes across cell membranes that are selective for potassium. The majority of cell types contain potassium channels, which regulate a wide range of cellular activities.
Potassium channels work to quickly (up to the diffusion rate of K+ ions in bulk water) and selectively transmit potassium ions down their electrochemical gradient (excluding, most notably, sodium despite the sub-angstrom difference in ionic radius).
In many cells, these channels function to either set or reset the resting potential. The delayed potassium ion counterflow in excitable cells, like neurons, alters the action potential.
