Question

Which phrase does NOT describe one of the functions of proteins of the plasma membrane?


-forming a channel through the membrane

-initiating the replication of the genetic material (CORRECT)

-binding to a substance to carry it through the membrane

-acting as a pump to move ions into and out of the cell.

-increasing the rate of a chemical reaction

The correct answered is marked above, but I am having a difficult time explaining why that is the correct answer compared to the others. Can someone please explain?

Answer 1

The correct answer is "initiating the replication of the genetic material" because proteins of the plasma membrane do not have this function. The other functions listed are all functions of proteins of the plasma membrane, such as forming a channel through the membrane, binding to a substance to carry it through the membrane, acting as a pump to move ions into and out of the cell, and increasing the rate of a chemical reaction.
