Some ________ Use Group Translocation as a Means of Transport

Question

Some ________ use group translocation as a means of transport.
A) eukaryotes
B) bacteria
C) archaea
D) protozoa
E) eukaryotes and prokaryotes

Accepted Answer

Group translocation is a mechanism of transport used exclusively by bacteria. In this process, the transported molecule is chemically modified while it is being transported across the cell membrane. This modification ensures that the molecule remains inside the cell and cannot diffuse back out, making it a useful mechanism for nutrient acquisition in bacterial cells. This transport mechanism is not found in eukaryotes, archaea, or protozoa.
