For the partial diploid you've created, f' i+ p+ oc z− y+ / i− p+ o+ z+ y− , you already know that the promoter sequences for copies are functional, so you can focus on the repressor proteins and operator regions that control expression. indicate the source of repressor protein and the operator region(s) to which it binds. then indicate how this affects expression of lac genes from the f' plasmid and from the bacterial chromosome.

bacterium is not correct

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.
