Microbial Metabolism Flashcards
This type of chemical reaction usually stores energy and is called endothermic; Small reactants to large products
Anabolism
This type of chemical reaction usually releases energy and is called exothermic; Large reactants to smaller products
Catabolism
The key to successful life depends on these; Provides a place for the reaction to occur; High degree of specificity
Enzymes
Reactant molecules are called
Substrates
The amount of energy required to overcome the resistance to a reaction is called:
Activation Energy
How can activation energy be overcome ?
Increase thermal energy to increase velocity, increase concentration of reactants to increase rate of molecular collisions, add a catalyst
These macromolecules can exist as chains called polymers. These chains are composed of similar subunits called monomers.
Proteins, Nucleic Acids and Carbohydrates
Made up of the monomer amino acids that around bound together with peptide bonds
Protein
Made up of the monomer nucleotides
Nucleic Acids
Made up of the monomer monosaccharides
Carbohydrates
Same number of elements, but different arrangement
Isomer
Same atoms arranged opposite of each other (Mirror Images)
Stereoisomer
Polypeptide form that completes very specific functions
Definition of a Protein
A relatively large chain of amino acids linked by peptide bonds
Polypeptide
The covalent union between two amino acids that forms between the amine group of one and the carboxyl group of the other. The basic bond of proteins
Peptide Bond
