Question

multiple choice question
in gram-negative bacteria, enzymes that synthesize peptidoglycan are found in ______.

○ the plasma membrane
○ the outer membrane
○ the cytoplasm
○ the periplasmic space

Explanation:

In Gram - negative bacteria, the peptidoglycan layer is located between the outer membrane and the plasma membrane, in the periplasmic space. The enzymes responsible for synthesizing peptidoglycan are found in the periplasmic space. The plasma membrane is mainly involved in other cellular processes like transport and energy generation related to the cytoplasm. The outer membrane has different functions like acting as a barrier and containing porins. The cytoplasm is the site of many metabolic reactions but not the synthesis of peptidoglycan in Gram - negative bacteria.

Answer:

D. the periplasmic space
