Description

Biology Professor (Twitter: @DrWhitneyHolden) describes the major differences in Gram-Positive bacteria cell walls and Gram-Negative bacteria cell walls, including peptidoglycan layers, inner wall zones and periplasm, plasma and outer membranes, lipopolysaccharide (LPS), and lipoteichoic acids. Common examples of both Gram-Positive bacteria and Gram-Negative bacteria are also described. Great for MCAT Biology Review! For more information on how Gram-Positive and Gram-Negative Bacteria are distinguished under a microscope using a Gram Stain, see Biology Professor's video: http://www.youtube.com/watch?v=1SITCrgF3yk
