,Question: 1
Pts
True Or False: The ΔG Value For A Particular Reaction Is -78 KJ/Mol. This Value
Indicates The Reaction Is Spontaneous.
A. True
B. False
ANS. A.
A Negative ΔG Value Indicates That A Reaction Releases Free Energy And Is Therefore
Thermodynamically Spontaneous. The Large Negative Value (−78 Kj/Mol) Strongly
Favors The Forward Reaction.
Question: 2
Pts
True Or False: A Biochemical Metabolic Pathway Is A Single Reaction That Converts
Starting Material Into Products.
A. True
B. False
ANS. B.
A Metabolic Pathway Consists Of A Series Of Enzyme-Catalyzed Reactions, Not A
Single Reaction, That Convert Substrates Step-By-Step Into Final Products.
Question: 3
, Pts
True Or False: Three ATP Molecules Are Used In The Energy-Investing Stage Of
Glycolysis.
A. True
B. False
ANS. B.
Only Two ATP Molecules Are Consumed During The Energy-Investment Phase Of
Glycolysis (At The Hexokinase And Phosphofructokinase Steps).
Question: 4
Pts
True Or False: The Citric Acid Cycle Occurs In The Presence Of Oxygen.
A. True
B. False
ANS. A.
While Oxygen Is Not Directly Used In The Citric Acid Cycle, The Cycle Depends On
Oxygen Indirectly Because Oxygen Is Required For The Regeneration Of NAD⁺ And
FAD In The Electron Transport Chain.
Question: 5
Pts
True Or False: The β-Oxidation Pathway Only Degrades Odd-Numbered Fatty Acids.
