1. All are linked to the electron-transport chain through Complex I accepting electrons from NADH EXCEPT:

a. gluconeogenesis

b. glycolysis

c. citric acid cycle

2. All are characteristics of the ATP synthase mechanism EXCEPT:

a. one site is empty (O-site)

b. one site contains ADP and Pi (L-site)

c. energy-driven conformational changes convert T-sites to O-sites

d. T-sites bind ATP

e. none of the above

d. all are true

Expert Solution

1. All are linked to the electron-transport chain through Complex I accepting electrons from NADH EXCEPT:

During various steps in glycolysis and the citric acid cycle, the oxidation of certain intermediate precursor molecules causes the reduction of NAD+ to NADH + H+ and FAD to FADH2. NADH and FADH2 then transfer protons and electrons to the electron transport chain to produce additional ATPs by oxidative phosphorylation

ANSWER:

Option a ( gluconeogenesis )

2. All are characteristics of the ATP synthase mechanism EXCEPT

ATP synthase is an enzyme that creates the energy storage molecule adenosine triphosphate (ATP). It is formed from adenosine diphosphate (ADP) and inorganic phosphate (Pi)

ANSWER:

Option e ( none of the above )
