Question

9 , What feature of eukeryotic cytoplasmic membranes differentiates it the most from prokaryotic cytoplasmic membranes? Prokeryotic cytoplesmic membranes do not contain phospholipids. The composition of the phospholipid layer facing the outside of the cell is significently different compared to the lipid layer facing the cytoplesm. Unique proteins penetreting the cytoplesmic membrane. (Hint are there unique cytoplasmic membrane-protein differences found in eukeryotic cells?) Eukaryotic cytoplasmic membranes do not contain phospholipids Staphylococcus species can be distinguished from Streptococcus, Enterococcus, and Lactococcus species on the basis of catalase activity True False Which of the following about bacterial diversity are FALSE? Squid and flashlight fish have specialized organs that carry nitrogen-fixing bacteria Cyanobacteria are Agrobacterium species Studies of bioluminscent carry plasmids with genes for a toxin that destroys plant cells bacteria lead to the discovery of quorum sensing The Ti plasmid of Squid and flashlight fish Agrobacterium species have specialized organs is used to geneticallythat carry bioluminescent engineer plants. bacteria
