Friday 11 December

Friday 11 December, we have game class first before we go to lecture. Everyone need to make flashcards on the topics microbial nutritional and microbial metabolism and share it on blenspace. And we make a group crossword quizzes on website proprofs and we enjoy play the quizzes game together in the class. I learn the definition of term like Metabolism, Catabolic reactions, Anabolic reactions  , Catabolism, Anabolism and Enzymes. The mechanism of enzyme action is Active site, Enzyme-substrate complex,transformation,release the products of the reaction,the unchanged enzyme is now free to react with other substrate molecules. Factors influencing enzymatic activity is temperature, pH and concentration and inhibitors. 2 aspects of energy production which is concept of oxidation-reduction and mechanisms of ATP generation. Oxidative phosphorylation is energy released as electrons are passed to a series of electron acceptors/carriers and finally to O2 or other inorganic or organic molecules. Photophosphorylation is energy from light is trapped by chlorophyll, and electrons are passed through a series of electron acceptors. I also know Cellular respiration of Aerobic respiration,Anaerobic respiration and Fermentation . lastly on this topic I can identify the alcohol fermentation and lactic acid fermentation.

There are 2 major nutritional concern which is Source of energy and Source of carbon. In Energy sources we have phototrophs which is light as primary energy source and chemotrophs is inorganic and organic compunds as primary energy source . in Combine the energy and carbon sources, there is Photoautotrophs,  Photoheterotrophs, Chemoautotrophs and Chemoheterotrophs.
