Unit 8024 Demonstrate knowledge of Bacterial Structure By Elysia Butler

Gram Positive Structure Peptidoglycan Cell Wall Cytoplasm Cytoplasmic Membrane Cell Section Enlargement = Within the peptidoglycan stand are teichoic acids and polysaccharides

Gram Negative Structure Cell Wall Cytoplasm Cytoplasmic Membrane Peptidoglycan Outer Membrane Section Enlargement = Cell The outer membrane contains Porin trimers, O antigens and Lipopolysaccharides. There is also a space between the Cytoplasmic Membrane and the Outer Membrane which is known as the Periplasmic Space
