Suppose that in a neuron, ena is +58mv: ek is -80mv, and vrest
is+50mv. what can you correctly assume about the
concentrationgradients and permeabilities for na+ and k+ in this
cell? circleall that apply
i) in this neuron, both na+ and k+ are at equilibrium whenthe cell
is at vrest.
ii) in this neuron, the external k+ concentration is greaterthan
the internal k+
concentration.
iii) in this neuron, the membrane is permeable to na + butnot to
k+.
iv) in this neuron, the k+ permeability of the membrane isless than
the na+ permeability.

sorry, but you do not have posted the diagram.

it provides an alternative energy pathway for the reaction to proceed.

a catalyst is a substance that speeds up the rate of a chemical reaction but is not consumed during the course of the reaction.

catalysts increase the rate of reaction without being used up. they do this by lowering the activation energy needed. with a catalyst, more collisions result in a reaction, so the rate of reaction increases. different reactions need different catalysts.

a catalyst works by providing an alternative reaction pathway to the reaction product. the rate of the reaction is increased as this alternative route has a lower activation energy than the reaction route not mediated by the catalyst.

then go eat. lol.brainliest

the most likely explanation for this is that his wounds have started to scab over and that stops the bleeding.
