Which of the Following is CORRECTLY Matched with Its Description

Question

Which of the following is CORRECTLY matched with its description?
A) Channel proteins - catalyze chemical reactions inside the cell
B) Cell identity molecules - are primarily steroids
C) Receptor proteins - move specific ions or molecules using ATP
D) Peripheral proteins - penetrate the lipid bilayer from one surface to the other
E) Carrier proteins - move bound ions or molecules from one side of the membrane to the other

Accepted Answer

Carrier proteins are indeed responsible for moving ions or molecules across the cell membrane, often changing shape to transport their cargo from one side to the other. This process can be either passive (not requiring energy) or active (requiring energy, often in the form of ATP).
