It has been discovered that this type of cell is found in humans and is more numerous in humans than there are human cells themselves. most of these are beneficial and aid in processes such as digestion and disease fighting, although some of them can be pathogenic. which of these types of cells is described here?

a)
bacterial

b)
eukaryotic

c)
protozoan

d)
viral

the match lol

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.
