5371851283Carbs-CHO 1-2-1 -monomer= glucose -polymer= groups of glucose -Bio examples= cell walls of plants: cellulose, chitin -Energy: 4cal/g, 1ST SOURCE0
5371851349Lipids-CHO (lots of C's and H's, little O's) -Monomer= fatty acids/ glycerol -polymers= saturated and unsaturated fats -Bio examples= blubber, phospholipid bilayer -Energy: 9cal/g, 2ND SOURCE1
5371853413Proteins-CHON -monomer= amino acids -polymer= polypeptides/ protein -Bio examples= hair, muscles, skin -Energy: 4cal/g, LAST SOURCE2
5371853414Nucleic Acids-CHONP -monomer= nucleotides -polymer= DNA, RNA -Bio examples= DNA and RNA -Energy: not a source of energy3
5371887843Primary Structureamino acids are joined together4
5372105423Primary interactionPeptide bonds join together amino acids (C-N)5
5371887844Secondary Structure3D shape -alpha helix -beta pleated shape6
5372126888Secondary interactionH-bond between amine group of one amino acid and the carboxyl group of another- (Hydrogen to oxygen)7
5371889522Tertiary StructureComplex globular shape due to R-group interactions8
5372148887Tertiary Interaction-hydrophobic interactions -van der waals -disulfide bridges (cysteins are attracted to each other) -enzymes hold them together9
5371889523Quaternary StructureMultiple tertiary structures put together10
5372161775Function of EnzymesTo lower the activation energy and start the reaction faster11
5372222662Structure of enzymes-Enzymes have to be specific to its substrate in order to fit -Substrate bonds to enzyme's active site12
5373454141Normal vs. Allostericnormal= one active site allosteric= more than one active sit13
5373832546catalyzed reaction14
5373461433Negative feedbackInhibition stops a biochemical pathway from making product.15
5373465286Competitive Inhibition-blocks the active site -competitor makes substrate unable to connect with active site16
5373471816Non-competitive Inhibitition-Binds to allosteric site and causes a conformational change in active site, so substrate can no longer bind17
5373483807Environmental factors that influence enzyme activity-temperature -pH -substrate concentration (increase substrate= no change in rxn rate) -enzyme concentration (increase enzyme= increase in rxn rate)18
5373846652Exergonic reaction-reaction is spontaneous -products have less energy -energy is released19
5373850744Endergonic reaction-reaction is not spontaneous -reactants have less energy -energy is absorbed20
5373814908Denaturing enzymepermanently deforming enzyme -active site no longer the correct shape -acids/bases change the bonding of R-groups in the active site -heat= destroys and changes shape permanently -cold= molecular movements decrease, less substrate/enzyme interaction21
5373584612Hydroxyl-OH -Polar -Hydrophilic -found in ALL Nucleic Acids22
5373598165Methal-CH3 -non-polar -hydrophobic -found in many lipids23
5373603719Carboxyl-COOH -polar -hydrophilic -acidic24
5373607541Carbonyl-CO -polar -hydrophilic -acidic25
5373622975Amine-NH2 -polar -hydrophilic -found in all proteins26
5373658924Sulfydryl-SH -polar -hydrophilic -forms disulfide bridges in proteins27
5373667817Phosphate-PO4 -polar -hydrophilic -phospholipids -ALL nucleic acids28
5373680906Dehydration synthesisputting monomers together to make polymers -creates H20 -forms peptide bonds29
5373706567Properties of water-Choesion -Adhesion -Solvent -High specific heat -high vaporization -Density- water is less dense when solid and most dense at 4 degrees C30
5373786462Acids-pH of below 7 -excess of H+ ions31
5373786463Bases-pH of above 7 -excess -OH ions32
5373796196Bufferssubstances that minimize changes in pH. Accept H+ from solution when they're in excess and donate H+ when they're depleted. -more acidic= H+ ions increasing, moves to left of rxn -more basic= -OH ions increasing, moves to right of rxn33
