B. The bacteria have an initial concentration of 1000 cells/cm3. Each cell divides once every 30 minutes.
Calculate how long it will take for the concentration to become greater than 15 000 cells/cm².

answer: all : )

explanation:

i believe your answer would be c.. : )

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.
