true - Answers -T/F: The majority of the reactions of the urea cycle occur in the cytosol.

false - Answers -T/F: The majority of the reactions of the urea cycle occur in the
mitochondrial matrix.

false - Answers -T/F: FADH2 yields 2.5 ATP molecules after donating electrons and
hydrogen atoms to the ETC.

2.5 ATP per NADH - Answers -How many ATP molecules does NADH yield after
donating electrons and hydrogen atoms to the electron transfer chain (ETC)?

1.5 ATP per FADH2 - Answers -How many ATP molecules does FADH2 yield after
donating electrons and hydrogen atoms to the electron transfer chain (ETC)?

true - Answers -T/F: ATP is invested in the urea cycle.

3 - Answers -How many total ATP are invested in the urea cycle?

false - Answers -T/F: There are 5 complexes associated with the ETC.

4 - Answers -How many complexes are associated with the ETC?

false - Answers -T/F: In the production of ATP via ATP synthase, the H+ ions move from
the mitochondrial matrix to the intermembrane space.

true - Answers -T/F: In the production of ATP via ATP synthase, the H+ ions move from
the intermembrane space to the mitochondrial matrix.

4 - Answers -The urea cycle involves ___ reactions (only those in the cyclic portion of
the process).
