false
in the mitochondrial matrix.
T/F: FADH2 yields 2.5 ATP molecules after donating elec-

trons and hydrogen atoms to the ETC.
How many ATP molecules does NADH yield after donating
electrons and hydrogen atoms to the electron transfer 2.5 ATP per NADH
chain (ETC)?
How many ATP molecules does FADH2 yield after donating
electrons and hydrogen atoms to the electron transfer 1.5 ATP per FADH2
chain (ETC)?
T/F: ATP is invested in the urea cycle. true

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