Cell Parts

• Lipopolysaccharides are also known as endotoxins.
• In prokaryotic ribosomes 50S + 30S = 70S.
• The glycocalyx can protect bacteria from the immune system.
• Disinfectants are meant for surfaces.  
• capsules have a defined shape and can be found in gram-positive and gram-negative cells
• Prokaryotes lack a nucleus and organelles
• Mice will die when injected with Smooth strain Streptococcus  pneumoniae and Smooth strain that have been heat killed and rough strain.
• E coli P fimbriae attach to P antigens.
• The glycocalyx of streptococcus pneumoniae allows it to be virulent.
• Bacterial chromosomes are larger than plasmids.
• Neisseria gonorrhea survives because it can change its fimbriae.
• Gram-negative bacteria have lipopolysaccharides.
• Ribosomes are used to make proteins.
• All cells have cell membranes
• A thick wall of Peptidoglycan is found in Gram-positive bacteria?
• Plasma (cell) Membrane and Teichoic Acid are found in Gram-positive bacteria?
• Integral membrane proteins are embedded in the plasma membrane because they have hydrophobic regions.
• Neisseria gonorrhoeae hides from the immune system by changing its fimbriae
• The glycocalyx can be used by bacteria to adhere to surfaces.
• Order from the inside of a bacterial cell to the outside


  Cell Membrane, Cell Wall, Outer Membrane, and Glycocalyx
• The fluid mosaic model refers to cell membranes
• Gram-negative bacteria have two phospholipid bilayers.
• Biofilms are caused by Glycocalyx
• Cell Membranes are found in all known cells
• Prokaryotes have circular chromosomes
• Autoclaves destroy endospores
• All living things have ribosomes.  
• The is glycocalyx involved in

  • Protect against Antibiotics
  • Attaching to surfaces
  • Protect against the immune system
• What layers surround the cytoplasm of Gram-negative cells going from the inside to the outside?

  Cell Membrane, Cell Wall, Outer Membrane
• Bacterial Cell walls are made of peptidoglycan
• Some prokaryotes may have Lipopolysaccharides
• Plasmids are made of DNA
• Eukaryotes consist of:

  • Animals
  • Yeast
  • Fungii
• Fungi and Yeasts have cell walls made of chitin
• Capsules and slime layers are types of glycocalicies
• Endospores can survive treatment with disinfectant and antiseptics. 
• Flagella and Fimbriae can be used by bacteria to move?
• Biofilms consist of cells and Glycocalyx.
• What is the shape of Eukaryotic chromosomes

  Linear
• What makes up the eukaryotic ribosome

  60S + 40S = 80S
