Medical biochemistry final exam questions
with correct answers
Competitive |inhibition |- |VERIFIED |ANSWER✔✔-competes |w/ |substrate |for |binding |to |the |active |site |
but |does |not |effect |catalysis |

- |Vmax |= |no |change

- |Km |= |increases |

- |LWB= |lines |intersect |at |y-axis



Uncompetitive |inhibition |- |VERIFIED |ANSWER✔✔-only |binds |to |the |ES |complex |and |does |not |affect |
substrate |binding |but |inhibits |catalytic |functions |

- |Vmax |= |decrease |

-Km= |decrease |

- |no |change |in |km/Vmax |

-LWB |= |lines |are |parallel



noncompetitve |inhibitor |- |VERIFIED |ANSWER✔✔-- |Vmax |= |decrease |

-Km |= |no |change



Free |energy |change |- |VERIFIED |ANSWER✔✔-(delta |G |) |the |amount |of |free |energy |released |(-DeltaG) |
or |absorbed |(+ |Delta |G) |in |a |reaction |at |constant |temperature |and |pressure |

- |Exergonic |= |- |Delta |G |

- |endergonic |= |+ |Delta |G



Enthalpy |(H) |- |VERIFIED |ANSWER✔✔-The |heat |content |of |a |system |at |constant |pressure



Entropy |(S) |- |VERIFIED |ANSWER✔✔-the |extent |of |randomness |or |disorder |in |a |system



When |Delta |H |and |Delta |S |are |both |negative |the |reaction |. |. |. |- |VERIFIED |ANSWER✔✔-enthalpically |
favored |but |entropically |opposed, |it |is |spontaneous |only |at |temperatures |below |T= |deltaH/deltaS
