Today lecture we finished out the external  and intracellular structure of prokaryote . We started with cell wall with their function and we learn again about gram positive and gram negative . We can conclude that gram positive will stain purple while gram negative will stain red,peptidoglycan many in gram positive and fewer in gram negative,teichoic acid present in gram positive but absent in gram negative, periplasmid space and outer membrane are absent in gram positive but both present in gram negative. Lastly, lipopolysaccharide none in gram positive and high in gram negative. Today , I don’t know why dr. always call my full name to answer that same questions . I will remember that question which is outer membrane consist of lipoprotein, lipopolysaccharides,phospholipids and porins that form channelsthat permit passage of molecule. And I remember the word ATYPICAL which means unusual which not have peptidoglycan and contain sterols. While in archaea contain peptidoglycan called pseudopeptidogycan . There are several differences between gram positive and negative in archaea and bacteria .Then , we have to open edmodo to do 2 questions on structure of prokaryote and its role .

question that we have to do in class

 I got problem internet connection to open it . so have to do it on my way to back home at Kelantan .We also watched video of active transport that I already learned it when matriculation .

 The substance are moved by transporter proteins from low to high concentration.ribosome which 70S ribosome and can be divide into small subunit-30S and large subunit-50S. That all for today lecture .have safe journey to my friends and my beloved dr. wan . See you all next Tuesday lecture and to dr.wandon’t  forget to bring rendang for us .
