There are four steps in bacterial conjugation. the second step is missing in this list.
1. special sex pilus connects two cells.
2.
3. each cell makes a complementary dna strand.
4. the cells separate.
which is the missing step for the process of conjugation described?
a. two new, identical cells are produced.
b. the cell membrane elongates and pinches off.
c. some dna moves from one cell to another.
d. a dna molecule attaches to the cell membrane.

c.Some DNA moves from one cell to another.

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.
