The periplasmic space or periplasm is a space between the inner cell membrane and external outer membrane of bacteria, or any other equivalent space in other organisms. It may constitute up to 40% of the total cell volume in gram negative species, and is drastically smaller in gram positive species. The space contains a loose network of peptidoglycan chains, as well as a gel containing hydrolytic and degradative enzymes.

Is the cell wall between the cell membrane and the nucleus?
No the cell wall is the outside layer of the cell surronding the cell membrane and nucleus.
What is the difference between cell wall of gram positive and gram negative bacteria.?
Gram positive bacteria cell walls have a thick layer of Peptidoglycan and no periplasmic space. Gram negative bacteria cell walls have inner and outter cytoplasmic membranes with a periplasmic space in between. these also have a thin layer of Peptidoglycan. The outter cytoplasmic membrane of gram negative bacteria contains lipopolysaccharides.
Is streptococcus gram or gram?
i think is gram + It is gram positive, usually occurring in chains and pairs of gram positive cocci. It is also a beta hemolytic organism, meaning it will completely lyse RBC's in a zone around individual colonies. If you are using a Mannitol Salt agar medium, in this zone then it will be transparent.
What us escherichia coli and what is it made of?
E. Coli is a gram negative bacteria part of the family enterobacteriace found in our G.I flora, just like any other gram negative bacteria it has a plasma membrane, periplasmic space, and an outer cell membrane. It has both exotoxin and endotoxin. It can cause travelers diarrhea, menningitis in the elderly and infants population. It is also the most common cause of urinary tract infection in women. Can be safely treated with 2nd or 3rd generation cephalosporins
Where was the planet Neptune born or discovered?
Discovered on September 23, 1846, by John Couch Adams. Neptune was the first planet found by mathematical prediction rather than by observation. Unexpected changes in the orbit of Uranus led astronomers to deduce that its orbit was subject to gravitational perturbation by an unknown planet. Neptune was subsequently found within a degree of its predicted position.Adams worked on his calculations at Cambridge and his home in Cornwall UK. Neptune was discovered on September 23, 1846 by Johann Gottfried Galle, of the Berlin Observatory, and Louis d'Arrest, an astronomy student, through mathematical predictions made by Urbain Jean Joseph Le Verrier
What is the periplasmic function?
Periplasmic is the name given to the area that is immediately near to a cell wall or bacteria. The main function of periplasmic space is permeability.
What is the periplasm?
Periplasmic is the name given to the area that is immediately near to a cell wall or bacteria. The main function of periplasmic space is permeability.
How does periplasmic space function?
Periplasmic space contains binding proteins for nutrient uptake and nutrient processing. It also contains enzymes that protect the cell against toxic chemicals.
Is there periplasmic space in both gram positive and gram negative?
The periplasm is a region in the cell wall of Gram-negative bacteria
Is the cell wall between the cell membrane and the nucleus?
No the cell wall is the outside layer of the cell surronding the cell membrane and nucleus.
What is periplasmic flagella?
Periplasmic flagella do not extend outside of the cell's outer membrane, but stay wrapped around the inner membrane compartment of the cell. These bacteria move by twisting their bodies like a cork screw. For more information about this, check out the spirochete flagella.

The outter cytoplasmic membrane of gram negative bacteria contains lipopolysaccharides.
What is the difference between g plus ve and g-ve bacteria?
Primarily, the difference lies in their cell walls. G+ve bacteria have a thick peptidoglycan layer whereas G-ve bacteria have an outer membrane of lipopolysaccharides and proteins, a periplasmic space, and only a thin layer peptidoglycan.
