MULTIPLE CHOICE


1. Wohler Showed That A Chemical Found Only In Living Organisms Can Be Made
From Inorganic Substances When He Synthesized:
A) Ammonium Cyanate
B) Amino Acids
C) Urea
D) Uric Acid
ANS: C

Feedback:
Urea Was The First Organic Compound Synthesized From Inorganic Materials,
Demonstrating That Organic Compounds Could Arise From Non-Living Sources.
; A) Ammonium Cyanate Is An Inorganic Compound; B) Amino Acids Can Be
Formed From Various Precursors, But Urea Is Specifically Significant In This
Context; D) Uric Acid Is A Nitrogenous Waste, Not Directly Synthesized From
Inorganic Sources.
Page Ref: Section 1-1

2. The Lock-And-Key Theory Described The Action Of:
A) Enzymes As Keys That Fit Different Chemicals.
B) Substrates As Keys That Fit Different Enzymes.
C) Enzymes As Locks That Fit Other Enzymes.
D) Substrates As Locks That Fit Different Enzymes.
ANS: B

Feedback:
This Theory Illustrates How Specific Substrates Fit Into Specific Enzymes, Much
Like A Key Fits Into A Lock.
; A) Enzymes Are The Locks, Not Keys; C) This Option Misrepresents The Roles Of
Enzymes And Substrates; D) This Incorrectly Reverses The Roles Of Enzymes And
Substrates.
Page Ref: Section 1-1

C) C, H, N
D) Fe, C, H, O, P
E) Ca2+, K+, Na+, Mg2+, Cl-
ANS: B

Feedback:
These Elements Are Fundamental To Biological Macromolecules And Thus
Constitute The Majority Of An Organism's Mass.
; A) Includes Less Significant Elements; C) Is Incomplete; D) And E) Also Include
Elements Not Primarily Found In Most Organisms.
Page Ref: Section 1-2

Structure.
; A) Amide Linkages Are Not Significant In Nucleotides; D) Ether Linkages Are Not
Typical In Nucleotides.
Page Ref: Section 1-2

7. Which Functional Group Is Shown?
A) Primary Amine.
