The proteins of bacteria that are involved in the movement of small molecules into the cell are called
A) transport proteins, carriers, AND peptidases.
B) transport proteins, permeases, AND carriers.
C) permeases, carriers, AND peptidases.
D) carriers, peptidases, AND porases.
E) peptidases, porases, AND permeases.

Question

Quizplus · Accepted Answer

Transport proteins, permeases, and carriers are all involved in the movement of small molecules across the bacterial cell membrane. Peptidases are enzymes that break down peptides and are not involved in transport. Porases are pore-forming proteins that allow passage of large molecules and are not specific to small molecule transport.
