Document Summary
Chapter 3 - nutrition, culture, and metabolism of microorganisms. Glucose:number one sugar you use in culture media. It is a carbon source, it is important in building the cell walls. Fructose:is an important energy source to the cells. Dna and rna are polymers of nucleotide monomers. Metabolism: the sum total of all chemical reactions that occur in a cell. Catabolic reactions ( catabolism ): energy releasing metabolic reactions. Anabolic reactions ( anabolism ): energy requiring metabolic reactions. Nutrients: supply of monomers required by cell for growth. Micronutrients: nutrients requited in trace amount, often referred to as trace elements. Essential for all microorganisms: h, c, n, o, p, s, se. ** should know the make up of a bacteria cells containing elements. Carbon makes up 50% of the dry weight. Protein is about 55% of the dry weight. Lipid is about 9. 1% of the dry weight. Polysaccharide is about 5. 0% of the dry weight.
