The periplasmic space is quizlet

WebbThe periplasmic space is the space seen between the plasma membrane and the outer membrane in the gram-negative bacteria. A very small periplasmic space between the plasma membrane and the peptidoglycan layer ( cell wall) may be observed in the gram-positive bacteria (Zuber et al., 2006). The periplasmic space is a lot thicker in Gram … WebbThe primary structural component of the bacterial cell wall is peptidoglycan, which is essential for viability and the synthesis of which is the target for crucial antibiotics 1,2.Peptidoglycan is a single macromolecule made of glycan chains crosslinked by peptide side branches that surrounds the cell, acting as a constraint to internal turgor 1,3.In …
