Question

Quizplus · Accepted Answer

The periplasmic space is an important reaction site for substances entering and leaving the cell, making it crucial for nutrient uptake, waste removal, and antibiotic resistance in gram-negative bacteria. It is located between the inner and outer membranes of gram-negative bacteria and contains a variety of enzymes and transport proteins. Gram-positive bacteria do not have an outer membrane or periplasmic space. The periplasmic space is not made up of lipopolysaccharides and phospholipids, but rather contains these components in the cell wall and outer membrane.
