question 80

Multiple Choice

In the presence of oxygen and in the absence of ADP,what occurs if the uncoupler 2,4-dinitrophenol is added to a suspension of normal mitochondria five minutes after an oxidizable substrate has been added?

• A)The substrate will be oxidized until the addition of the 2,4-dinitrophenol,which blocks further oxidation.
• B)There is no effect;oxidation of the substrate continues at the same rate before and after the addition of 2,4-dinitrophenol.
• C)The substrate cannot be oxidized either with or without 2,4-dinitrophenol unless ADP is also present.
• D)Oxidation of the substrate does not occur until the 2,4-dinitrophenol is added.Afterward,oxidation proceeds rapidly until all of the substrate is consumed.
