Document Summary
Chemical energy: weak bonds w/ equally shared electrons - high pe, strong equally shared bonds = low pe. Determines whether a reaction is spontaneous or requires energy to proceed. If change in g < 0, spontaneous (less energy in products) If change in g > 0, requires energy (products have more energy than reactants) Complete highly exergonic rxns (energy released) w/ an endergonic reactions (requires energy to proceed) Releases energy (exergonic) - 7. 3 kilocalories per mole of atp - 1 kg of. Couple endergonic rxn w/ hydrolysis of atp. Provides energy to split one endergonic reaction. Enzymes - protein catalysts which speed up and control biological reactions - must allow them to bind correctly and must have enough energy to overcome repulsion between electrons. Fig 8. 10: bring substrates together in specific positions, very specific: usually only catalyze one reaction, substrates bind to enzymes active site, hold substrates together and assists in correct interaction.
