12596412180anabolicsynthesis-build up reactions-0
12596412181catalysisthe acceleration of a chemical reaction by a catalyst.1
12596412182chemical bondsRepresent stored energy2
12596412183Reduction reactionIn chemistry- The gain of electrons3
12596412184Oxidation reactionsThe loss of electrons4
12596412185(CH4 or CO2) which one is more highly reduced and which is more highly oxidized-CH4 is more highly reduced- has a lot of reducing power -CO2 Is more highly oxidized- has little reducing power??????????????5
12596412186Electrochemical gradientsgradient is the difference in concentration - Difference of electron concentration in compared to one place to another - Always flow from high to low energy (*think of battery)6
12596412187ATP (Adenosine Triphosphate)-when cellular work needs to be done the cell uses ATP - High amounts of energy are stored in The extremely rich peptide bonds7
12596412188Are enzymes written into chemical equations? If so where...they are but written on the arrow separating the equations8
12596412189Active sitesThe part of the enzyme that actually does the job9
12596412190What is the chemistry term for enzyme?catilist10
12596412191Are enzymes consumed during the reactionNo they act as a "middle man" Reactants get attached, a product is formed , the reactants the detach11
12596412192what does an enzymes relies on to do its jobMacanics and probability - Enzymes require the components to be in the correct orientation to create a product12
12596412193How can an enzyme function be controlleduse an inhibitor13
12596412194(Ea)Activation energy- The energy required to start a reaction - The energy required to contort the reactant molecules so the bonds can break - The energy required to push the reactants to the top of an energy barrier so the downhill part of the reaction can began - activation energy is often supplied by heat in the form of thermal energy that the reactant molecules absorb from there surroundings - The absorbtion of thermal energy accelerates accelerates the reactant molecules so they colide more and more forcefully14
12596412195enzymes do what to the Ea of a reactionThey decrease the (Ea) barrier by hundreds of thousands of times. allowing the molecules to absorb enough energy to reach the transition state even at moderate temeratures15
12596412196After en enzyme is used once what happens to itThe enzyme stays intact and on goes the reactios16
12596412197phosphate groupOn the end of ATP and ADP - Releces a high amount of energy when broken away from the ATP because of H2O. - extremely elextronegative -phosphate bonds are referred to as high energy phosphate bonds17
12596412198The cells proteans harnis the energy releced by atp in several waysATP is used to drive chemical reactions - transpertation and michanical work are almost nearly powered by atp18
12596412199what drives most celular workChemical potential energy stored in ATP drives most cellular work19
12596412200Where does the free energy required to Phosphorylate ADp come fromIt comes from the exergonic breakedown reactions called Catabolism in the cell (such as cellular respiration) - The atp cycle accures at an astonishing rate, muschle group can recycle all its atp in less then a minute.20
12596412201Active SiteThe part of the enzime that does the job of arranging the substrate21
12596412202the substratethe substrate is the molecule that fits into the enzyme22
12596412203induced fitthe enzime cups the substrate when its inside23
12596412204cofactor or coenzyme-helps enzimes -non-protean helpers that meny enzymes require, sometimes copper, zinc or iron24
12596412205inhibitorsInhibit with the actions of a specific enzyme25
12596412206competitive inhibitorsreduce the productivity of enzymes by blocking substrates from entering the active sites so they become less available26
12596412207noncompetitive inhibitordo not directly compete with the substrates to bind to the enzyme at the active sites but incited bind to the enzyme in other places causing it to change its shape becoming less effective at catolosis27
12596412208whats a waste product of respirationcarbon Dioxide28
12596412209energy flows in as sunlight and leaves as >>>heat!!!!29
12596412210what are catabolic pathwaysCatabolic pathways are medibolic pathways that releace storred energy by breaking down complex molecules30
12596412211fermentationa catabolic process that accrues without oxygen - not the most efficient31
12596412212Aerobic ResperationThe most effective catibolic pathway - oxygen is consumed as a reactant along with organic fuel32
12596412213What is the point of glycolosisIt is to produce more ATP and NADH33
12596412214Glycolysis-Glycolysis in which the carbohydrate Glucose is oxidized - ATP is produced & NAD is reduced to NADH34
12596412215Where does Glycolysis occureGlycolysis Occurs in the cytosol35
12596412216GlucoseA highly reduced molecule -RICH in potential energy36
12596412217NAD^+A Coenzyme, (electron carrier ) -NAD^+ goes to NADH37
12596412218Glycolysis Consumes ATP to produce ATP???? WHYFor every molecule of glucose metabolized via Glycolysis -2 ATP Molecules are produced -2 NAD Molecules are reduced (2NAD->2NADH) -2 Pyruvate molecules remain38
12596412219metabolismthe sum product of the anabolic and catabolic processes in a living system39
12596412220anabolicbuilding up40
12596412221catabolicbraking down41
12596412222how can energy be stored in a biological system- chemical bonds -reducing power -electrochemical gradiants42
12596412223Krebs Cycle- occures in matrex of mitocondra - produces lots of ATP43
12596412224in anerobic cells the electrons alternately get accepted byO244
12596412225ATP SinthaseCarries the reaction in the mitocondra which converts ADP to ATP45
