Multiple Choice
Gram-negative cells contain a periplasmic space that is:
A
filled exclusively with ribosomes
B
found outside the outer membrane
C
located between the inner cytoplasmic membrane and the outer membrane
D
absent in gram-negative bacteria
검증된 단계별 안내1
Understand the structure of Gram-negative bacteria, which have two membranes: an inner cytoplasmic membrane and an outer membrane.
Recall that the periplasmic space is a distinct compartment in Gram-negative bacteria, located between these two membranes.
Recognize that the periplasmic space contains various enzymes and proteins, but not ribosomes, which are found in the cytoplasm.
Note that the periplasmic space is not outside the outer membrane; rather, it is enclosed between the inner and outer membranes.
Conclude that the correct description of the periplasmic space is that it is located between the inner cytoplasmic membrane and the outer membrane.
