    Recall that the complete oxidation of a mole of glucose releases 686 kcal of energy (

    ΔG=- 686 kcal/mol). The phosphorylation of ADP to form ATP stores approximately 7.3 kcal per mole of ATP. What is the approximate efficiency of cellular respiration for a "mutant" organism that produces only 29 moles of ATP for every mole of glucose oxidized, rather than the usual 36-38 moles of ATP?

    A) 0.4%

    B) 25%

    C) 30%

    D) 40%

    E) 60%


    C) 30%

    Exposing inner mitochondrial membranes to ultrasonic vibrations will disrupt the membranes. However, the fragments will reseal "inside out." These little vesicles that result can still transfer electrons from NADH to oxygen and synthesize ATP. If the membranes are agitated still further however, theability to synthesize ATP is lost.



    After the first disruption, when electron transfer and ATP synthesize still occur, what must be present?

    A) all of the electron transport proteins as well as ATP synthase

    B) all of the electron transport system and the ability to add CoA to acetyl groups

    C) the ATP synthase system is sufficient

    D) the electron transport system is sufficient

    E) plasma membranes like those bacteria use for respiration


    A) all of the electron transport proteins as well as ATP synthase

    B) the prosthetic groups like heme from the transport system

    C) cytochromes

    D) ATP synthase, in whole or in part

    E) the contact required between inner and outer membrane surfaces
