 In the  morning we went to National University Carnival on E-learning at SACC, Shah Alam. We went there for supporting our friends who involve in the Carnival.We went there by bus. I get to see many booth from UPM and other university take part in the carnival in many field such as medicine, earth science, communication and many more.There are many new information that I get when visiting the booth. I also get to see many different way of learning during the carnival. I enjoys myself at the carnival. Thank to Dr Wan who bring we here and also congrats to our friends who manage to get Silver in the competition.






In the evening we have class with Datin Khadijah at 1.3. We learn about Regulation of Gene Expression.
Modes of Gene Expression
-constitutive expression
  • expressed at same rate all time
-inducible expression
  • gene expression changes in response to condition.
Regulation of enzyme activity
Feedback inhibition

Allosteric inhibition

Prokaryotic Regulationn
  •  specialized cell types
  • save energy: turn off unnecessary genes
  • respond quickly to changing condition
When learning about this I realize  that all the gene have been controlled in our body all the times.It quickly react to make our body always stable. I just realize that many process involve in regulating our body.

What I have learn:
-In feedback inhibition the end product of the biosynthesis pathway inhibits the activity of the first enzyme.

-Organisms may not wish to express all genes all the time.

-Allosteric inhibition responsible for end product inhibition

26/9/14  Today we have our class at 8 o'clock early than the usual. We learn about External structure of prokaryote. I  a little bit shock when knowing we going to learn about external structure of prokaryote because we just send our mind map about internal structure of prokaryote. Anyway the class carry on and I have fun learning about external structure of prokaryote.   Prokaryotes are a group of organisms that lack of cell nucleus or any other membrane bound organelle. The two domains in prokaryote are bacteria and archaea. Three basic shapes coccus Arrangement : diplococci, staphylococci, streptococci, tetrads, sarcinae pic from:http://images.books24x7.com/bookimages/id_20695/fig153_01.jpg   Bacillus Arrangement: diplobacilli and streptobacilli   Spiral arrangement:vibrio, spirilium and spirochetes The smallest bacteria is mycoplasma. Vibrio cholera cause cholera which  cause watery diarrhea and vomiting. This bacteria comes from water contaminated by

The second chapter we learn about cell wall and membrane structure of prokaryote. Flagella is long filamentous appendages that propel bacteria. from: http://i0.wp.com/microbeonline.com/wp-content/uploads/2013/04/flagellar-arrangement-of-bacteria.jpg I wonder if the number and arrangement effect the movement? There are three basic part Filament hook basal body Axial filament are bundles of fibrils that arise at the end of cell beneath the outer sheath.Present in spirochetes group of bacteria What I have learn: Gram negative cell wall have few layer of peptidoglycan Gram positive have teichoic acid. Archaea have pseudomurein

relate Microbial Ecology to other microbiology courses have covered and apply the knowledge in the future

 In previous subject I learn  their characteristics and uses. When I am studying Microbial ecology I get to know more about the place that I learn their characteristics  and uses. I also study lab of microbiology with the knowledge from both course I should be able to know how to find and isolate microbes. Different microbes stay in different places. Different microbes require different way to isolate them. For the future application, I think to solve a problems using microbes, the microbes that will solve the problems need to be find in the problems occur. For example, bacteria that involve in bio remediation usually live and isolated in polluted area since there are able to withstands the pollutants.
