Bacteria are grouped into two catgories reflecting structural features of their cells. Bacteria are classified as Gram-positive or Gram-negative based on whether or not they retain the crystal violet dye used in the Gram stain procedure. Cell wall structure determines the ability to retain the dye, thus cell wall structure is the basis of categorization into Gram-postive (G+) and Gram-negative (G-).
Which of the following occurs only in Gram-negative bacteria?
(A) Peptidoglycan
(B) Integral proteins
(C) Lipoteichoic acid
