<span>The right answer is: they work by blocking sodium channels in the cell membrane.
These drugs are used systemic and not local.
</span>they block sodium channels in the cell membrane in the synapses between neurons, and not along axons.
Many drug acts by blocking sodium channel, in a specific location, like antiepileptics in the nervous system, and digoxin and antiarrhythmic in the heart.
Facilitated diffusion. It is a passive transport mechanism in which carrier proteins shuttle molecules across the cell membrane without using the cell’s energy supplies. Instead, the energy is provide by the concentration gradient, which means that molecules are transported from higher to lower concentrations, into or out of the cell. The carrier proteins bind to glucose, which causes them to change shape and translocate the glucose from one side of the membrane to the other. Red blood cells use facilitated diffusion to absorb glucose.
TGCATGG because A pairs with T ( I remember with apples in the tree) and C pairs with G ( I remember this one with cars in the garage)
