Adding a chemical that reduces na+ transport near the sinoatrial (sa) node would have what effect on the heart's intrinsic conducting system?

Depolarization must be carried out at the sinoatrial node in order for the heart to beat. This depolarization occurs due to the movement of sodium ions through the cell membranes of the cells in the sinoatrial node. If a chemical reduces the transport of sodium ions, the sinoatrial node will depolarize less quickly, meaning the person's heart rate would slow down.

I’m pretty sure it’s false i’m not sure

Answer:

a. energy is absorbed in the reaction.

explanation:

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
