In one species, this structure is held together by bridges made of five glycine molecules. Beta lactam antibiotics act by preventing the synthesis of this structure. In bacteria, this structure's constituents are shuttled to the site of synthesis by bactoprenol. The Casparian strip runs along this structure in plants. This structure's arrangement determines whether bacteria are gram positive or negative and for them, it is composed of peptidoglycan. In plants, it is made of cellulose. For 10 points, name this protective layer of the cell, which usually surrounds the cell membrane.
