MICROBIAL NUTRITION (3) Basic Nutritional Requirements for Microbial maturement: descent of Nutrients informant of faculty Source of Electrons (e-) or hydrogen atoms that donate e- I. Source of Nutrients / (carbon) the basic lay downing blocks manipulationd by microbes to build/ compound new cadre components ? basic building blocks be the elements from the diurnal Table. Includes: ? Macroelements elements that are required in large amounts for increase (make up 95% of dry cell weight no water): carbon, hydrogen, oxygen, nitrogen, phosphorus, potassium, calcium, iron, magnesium, randomness ? Microelements or Trace Elements elements required for growth, but just in really small amounts: copper, cobalt, nickel, zinc, manganese Classification of Microbes by Carbon Requirement: A. Autotrophs (self-fed) microbes employ carbon dioxide (CO2) as sole source of carbon. B. Heterotrophs (mix-fed) microbes engagement some diverse organic co mpounds as their source of carbon (Ex. glucose, aminic acids, purines, and pyrimidines). II. Source of postal code the potentiality/ability to do work. oeuvre by cells may implicate: A.Biosynthesis of macromolecules/new cell components B.Active Transport C.
Motility To pay for work, cells use adenosine triphosphate (Adenosine Triphosphate): adenosine triphosphate ? ADP + Pi (phosphate group) + cogency to do work How do cells get adenosine triphosphate? ADP + Pi + Energy ? ATP Where does Energy to become ATP come from? (2) Strategies/Classification for E nergy to throw ATP: 1. Phototrophs (ligh! t-fed) microbes use energy from sunshine to create ATP through Photosynthesis. H2O + CO2 + sunlight (energy) ? C6H12O6 (glucose) + O2 - Energy from sunlight switch overed into chemical energy, stored in bonds of glucose. -These microbes must in a flash convert chemical energy in glucose into more businesslike high-power bonds of ATP. -Glucose will be oxidized (break down) and energy converted to ATP. 2.Chemotrophs (chemical-fed) microbes use chemical...If you want to get a full essay, baffle it on our website: BestEssayCheap.com
