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!
