Prokaryotic Cells – smaller than the eukaryotic cell and less complex; genetic material is located in the nucleiod which continuous circular piece of DNA and mostly has a cell wall with peptidoglycan; they can also have ribosomes and flagella (a long fiber that propels the cell). Plasma membrane – outer envelope of a cell; is a phospholipid that is semi-permeable membrane that regulates what enters and exits the cell Peripheral proteins – proteins loosely associated with the lipid bilayer Integral Proteins – proteins located on the inner or outer surface of the membrane Transmembrane protein – Fluid Mosaic Model – Adhesion Proteins – membrane proteins that from junctions between adjacent cells Receptor Proteins – proteins that serve as docking sites for proteins of the extra cellular matrix or hormones Transport Proteins – some proteins form pumps that use ATP to actively transport solutes across a membrane Channel Proteins – proteins that form channels that selectively allow the passage of certain ions or molecules Recognition and adhesion proteins - some proteins such as glycoproteins are exposed on the ETC surface and play a role in cell recognition and adhesion Carbohydrate Side-chains – a carbohydrate attached to a protein
