Biochem Module 8 Exam UPDATED ACTUAL QUESTIONS AND CORRECT
ANSWERS
true T/F: The majority of the reactions of the urea cycle occur in the cytosol.
false T/F: The majority of the reactions of the urea cycle occur in the mitochondrial
matrix.
false T/F: FADH2 yields 2.5 ATP molecules after donating electrons and hydrogen
atoms to the ETC.
2.5 ATP per NADH How many ATP molecules does NADH yield after donating electrons and
hydrogen atoms to the electron transfer chain (ETC)?
1.5 ATP per FADH2 How many ATP molecules does FADH2 yield after donating electrons and
hydrogen atoms to the electron transfer chain (ETC)?
true T/F: ATP is invested in the urea cycle.
3 How many total ATP are invested in the urea cycle?
false T/F: There are 5 complexes associated with the ETC.
4 How many complexes are associated with the ETC?
false T/F: In the production of ATP via ATP synthase, the H+ ions move from the
mitochondrial matrix to the intermembrane space.
