H is a thick letter: H zone has only thick filaments
A is a hybrid of “I” and “H”: A band has both thin and thick filaments (remains constant during contraction)

Cell Wall Synthesis Inhibitors A peptidoglycan monomer consists of 2 joined amino-sugars, N-acetyl glucosamine (NAG) and N-acetyle muramic acid (NAM), with a pentapeptide coming off of the NAM. So, a peptidoglycan monomer is a NAG-NAM-pentapeptide. These peptidoglycan monomers are synthesized in cytosol and transported across cytoplasmic membrane by Bactoprenols (BP)….
Nice.
thank you omg! this is so helpful
