,Question: 1
pts
True Or False: The Majority Of Reactions Of The Urea Cycle Occur In The Cytosol.
A. True
B. False
ANS. A.
Although The First Steps Of The Urea Cycle Occur In The Mitochondria, Most Reactions
(The Cyclic Portion) Take Place In The Cytosol, Making This Statement True.
Question: 2
pts
True Or False: FADH₂ Yields 2.5 ATP Molecules After Donating Electrons And
Hydrogen Atoms To The Electron Transfer Chain (ETC).
A. True
B. False
ANS. A.
Modern ATP Yield Estimates Show That FADH₂ Produces Approximately 2.5 ATP,
Slightly Less Than NADH Because It Enters The ETC At Complex II.
Question: 3
pts
True Or False: ATP Is Invested In The Urea Cycle.
, A. True
B. False
ANS. A.
The Urea Cycle Requires ATP Input To Activate Intermediates, Making It An Energy-
Consuming Pathway Essential For Detoxifying Ammonia.
Question: 4
pts
True Or False: There Are Five Complexes Associated With The ETC.
A. True
B. False
ANS. A.
The ETC Consists Of Complexes I–IV Plus ATP Synthase (Complex V), Totaling Five
Complexes.
Question: 5
pts
True Or False: In The Production Of ATP Via ATP Synthase, The H⁺ Ions Move From
The Mitochondrial Matrix To The Intermembrane Space.
A. True
B. False
ANS. B.
