Which activity is not a function of white blood cells in response to an invasion of the body by bacteria?

speeding transmissions of nerve impulses to detect bacterias.

Explanation:

Leukocytes or white blood cells (neutrophils, monocytes, eosinophils, basophils and lymphocytes) are produced in the bone marrow and have the function of fighting viruses, germs and bacteria in the blood system. Healthy people usually have a count of 7,500 leukocytes per cubic millimeter of blood; Adding more than 11,000 leukocytes per cubic millimeter of blood is called leukocytosis. This may indicate that the body requires more leukocytes in peripheral blood for an infection, for an inflammation by hyperproduction of these cells in the bone marrow. The latter may indicate a leukemia.

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.
