Types of metabolite

Extracts from this document...


´╗┐Distinction 2 A primary metabolite is a kind of metabolite that is directly involved in normal growth, development, and reproduction. A common example of primary metabolite is alcohol which is produced by microbiologists in labs. Ethanol is another example of primary metabolism Secondary metabolites are organic compounds that are not directly involved in the normal growth, development, or reproduction of an organism. Pigments and antibiotics are both common examples of secondary metabolisms. http://dc386.4shared.com/doc/ExLof9an/preview_html_76978fca.png Look at the time the two different types are produced, why do you think it?s important for scientists to know what kind of metabolite a product is? Primary metabolites are a really important component in maintaining normal physiological processes. These Primary metabolites usually produced during the growth phase as a result of energy metabolism, and are deemed essential for proper growth. ...read more.


However, some secondary metabolites can be important to scientists in the lab and some examples of these types of secondary metabolites are atropine and antibiotics such as erythromycin and bacitracin. It is important for a scientist to know what type of metabolite a product is because some type of metabolite like the primary metabolite are really crucial for growth and development and reproduction, this therefore makes primary metabolites important for growing cultures of bacteria. Distinction 3 http://www.smccd.net/accounts/case/biol230/growth/growthcurve.jpeg The lag phase The lag phase is the period of time between the birth of a microorganism into a culture medium and the time it begins to increase exponentially The log / exponential growth phase The log Phase of a bacteria growth is where all the cells are dividing regularly, and are growing rapidly at a constant, exponential rate. ...read more.


The generation time The generation time is how long it takes bacteria to grow and divide rapidly multiply, the generation time I obtained from my graph was 1 hour which was between 10 and 11 hours. This indicates that it takes a full hour for a cell to multiply every time. It is important to know the generation time of a microorganism because it helps to know when exactly a bacterium can grow and spread easily and how fast the bacterium will do it. For example, if a scientist wants carry out an experiment on bacteria, he needs to know how many starter bacteria to use, and how long to grow it will take for them to grow, in order to get enough bacteria for an experiment and carry out the experiment efficiently.
