7169228663Primary protein structuresequence of a chain of amino acids23
7169229909Secondary protein structureHydrogen bonding of the polypeptide back bone causes the amino acids to fold into repeating patterns24
7169235496Tertiary protein structureThre dimensional folding pattern of a protein due to side chain interactions25
7169237120Quaternary protein structureprotein consisting of more than one amino acid chain26
7169244780Non Enzymatic Protein FunctionThey function as antibodies, apart of the adaptive immune response; they can also be cell surface receptors27
7169257793EnzymesProtein folded into a specific 3-Dimensional shape to act as a catalysts28
7169259521Active SitesArea in the protein that performs catalysis with the reaction's substrates29
7169264196CatalysisA biochemical reaction facilitated by an enzyme for conversion of reactants into products30
7169265871CatalystsA material that increases the rate of a reaction by lowering the activation energy31
7169271211Active Site Model (Lock and Key)A theory suggesting the enzymes and substates are a perfect fit for each other.32
7169273976Induced Fit ModelThe substrate and the binding site differ slightly and binding induces conformational change33
7169278803Feedback InhibitionWhen an intermidiate or end product inhibits one of the other enzymes that proceed it. This prevents wastful over production of the product.34
7169282917Covalent ModificationAddition or removal of different groups in order to active or inactivate an enzyme35
7169285103Proteolytic CleavageThis is for enzymes such as zymogen which are synthesized in an inactive state and must be cleaved into activation by a protease36
7169298772ConstitutiveThe enzyme subunit is removed37
7169301242Allosteric RegulationModification of the active-site activity by interaction of molecules with other specific sites38
7169303602Allosteric SitesWhere the interaction with other molecules takes place39
7169305329CompetitiveInhibitors can compete for the binding site and out compete the substrate if the concentration is high enough40
7169310972Noncompetitive InhibitorsBinds at the allosteric sit, not the active site, and it won't budge even if the substrate is in high concentration41
7169314633Uncompetitive InhibitorsCan only bind to the enzyme-substrate complex42
7169316432Mixed-type inhibitorsCan bind to the unoccupied enzyme or the enzyme-substrate complex43
7169322085Michaelis-MentenRate of metabolism of a drug at or near saturation44
7169323167CooperactivityThe binding of one subunit to an enzyme allosterically increases the affinity for the next subunits or substrate, leading to a sigmoidal kinetic graph45
7169340461BioenergenticsThe production and utilization of energy in a biological system that all boils down to reduction and oxidation reaction46
7169344090MonosaccharideA single carbohydrate molecule. The carbons in monosaccharides are numbered from the carbon at the most oxidized end of the molecule. They can exist as a chain or a ring47
7169358782DisaccharideTwo disaccharides bind together though a dehydration reaction called glycosidic linkage48
7169365331Oligosaccharide, Polysaccharidesmultiple disaccharides conected through glycosidic bonds49
7196091838GlycolysisOccurs in the cell cytoplasm converting 1 Glucose into 26-28 ATP50
7196103841FermentationThe process of converting pyruvate into either ethanol or lactose51
7198933470GlycogenolysisThe break down of glucose polymer, glycogen, this is done so individual glucose ,molecules can be used for cellular respiration52
7198947919GluconeogenesisThe synthesis of glucose when the molecule diet wise is unavailable53
