- Penicillin inhibits bacterial growth by preventing the cross-linking during peptidoglycan synthesis. Why does penicillin not inhibit growth of archaeal cells? Group of answer choices Most archaeal cells have a cell wall, but it is not composed of peptidoglycan. Archaeal cells do not have a cell wall. Penicillin is unable to penetrate the lipid outer membrane that blocks access of penicillin to the peptidogycan crosslinking enzymes. Pencillin is unable to penetrate the S layer to reach the peptidoglycan layer underneath.arrow_forwardThe microbes discovered in Lake Whillans and Pitch Lake represented a few of the general categories of microbial life.
