Preface viii
Chapter 1. The Foundations of Biochemistry
ALL CHAPTERS HAVE MULTIPLE CHOICE AND EXPLAIN/DESCRIBE QUESTIONS

MULTIPLE CHOICE
1. In A Bacterial Cell, The DNA Is In The:
A) Cell Envelope.
B) Cell Membrane.
C) Nucleoid. (correct)
D) Nucleus.
E) Ribosomes.
ANS: C
In bacterial cells, DNA is located in the nucleoid region, which is not membrane-bound like a nucleus
in eukaryotic cells. This allows for efficient replication and transcription in a simpler cellular structure.

2. A Major Change Occurring In The Evolution Of Eukaryotes From Prokaryotes Was The
Development Of:
A) DNA.
B) Photosynthetic Capability.
C) Plasma Membranes.
D) Ribosomes.
E) The Nucleus.
ANS: E
The development of the nucleus allowed for the compartmentalization of genetic material, which is a significant
advancement over prokaryotic cells. This compartmentalization supports more complex gene regulation and
cellular processes.

3. In Eukaryotes, The Nucleus Is Enclosed By A Double Membrane Called The:
A) Cell Membrane.
B) Nuclear Envelope.
C) Nucleolus.
D) Nucleoplasm.
E) Nucleosome.
ANS: B
The nuclear envelope consists of two lipid bilayers and is crucial for protecting the genetic material while
regulating transport in and out of the nucleus.

4. The Dimensions Of Living Cells Are Limited, On The Lower End By The Minimum Number
Of Biomolecules Necessary For Function, And On The Upper End By The Rate Of Diffusion
Of Solutes Such As Oxygen. Except For Highly Elongated Cells, They Usually Have Lengths
And Diameters In The Range Of:
A) 0.1 M To 10 M.
B) 0.3 M To 30 M.
C) 0.3 M To 100 M.
D) 1 M To 100 M.
E) 1 M To 300 M.
ANS: C
Most cells, with the exception of highly elongated ones like neurons, typically range from 0.3 to 100
micrometers. This size range allows for adequate surface area-to-volume ratio for nutrient uptake and waste
removal.

5. Which Group Of Single-Celled Microorganisms Has Many Members Found Growing In
Extreme Environments?
A) Bacteria
B) Archaea
C) Eukaryotes
D) Heterotrophs
E) None Of The Answers Is Correct.
ANS: B
Archaea are well-known for their ability to thrive in extreme environments, such as high salinity,
temperature, and acidity, due to their unique biochemistry and cell structures.

6. The Bacterium E. Coli Requires Simple Organic Molecules For Growth And Energy—It Is
Therefore A:
A) Chemoautotroph.
B) Chemoheterotroph.
C) Lithotroph.
D) Photoautotroph.
E) Photoheterotroph.
ANS: B
E. coli is classified as a chemoheterotroph because it obtains energy from organic compounds and
requires them for growth. This distinguishes it from autotrophs that can synthesize their own food.

7. Which Is A List Of Organelles?
A) Mitochondria, Chromatin, Endoplasmic Reticulum
B) Peroxisomes, Lysosomes, Plasma Membrane
C) Proteasomes, Peroxisomes, Lysosomes
D) Mitochondria, Endoplasmic Reticulum, Peroxisomes
E) All Of The Answers Are Correct.
ANS: D
Option D lists only organelles. The others include non-organelle components (like chromatin and the
plasma membrane), which are not classified as organelles.

8. Which List Has The Cellular Components Arranged In Order Of INCREASING Size?
A) Amino Acid < Protein < Mitochondrion < Ribosome
B) Amino Acid < Protein < Ribosome < Mitochondrion
C) Amino Acid < Ribosome < Protein < Mitochondrion
D) Protein < Amino Acid < Mitochondrion < Ribosome
E) Protein < Ribosome < Mitochondrion < Amino Acid
ANS: B
Option B correctly arranges these components from smallest to largest. Amino acids are the building
blocks of proteins, which are larger, while ribosomes are larger than proteins, and mitochondria are the
largest structures in this list.

9. The Three-Dimensional Structure Of Macromolecules Is Formed And Maintained Primarily
Through Noncovalent Interactions. Which One Of The Following Is NOT Considered A
Noncovalent Interaction?
A) Carbon-Carbon Bonds
B) Hydrogen Bonds
C) Hydrophobic Interactions
D) Ionic Interactions
E) Van Der Waals Interactions
ANS: A
Carbon-carbon bonds are covalent bonds, which involve the sharing of electron pairs between atoms. In
contrast, hydrogen bonds, ionic interactions, and Van der Waals interactions are examples of noncovalent
interactions, which are generally weaker and play crucial roles in the stability of macromolecular structures.

10. Which Element Is NOT Among The Four Most Abundant In Living Organisms?
A) Carbon
B) Hydrogen
C) Nitrogen
D) Oxygen
E) Phosphorus
ANS: E
The four most abundant elements in living organisms are carbon, hydrogen, nitrogen, and oxygen.
Phosphorus, while important, is less abundant than the other four.

11. The Four Covalent Bonds In Methane (CH4) Are Arranged Around Carbon To Give Which
Geometry?
A) Linear
B) Tetrahedral
C) Trigonal Bipyramidal
D) Trigonal Planar
E) Trigonal Pyramidal
ANS: B
Methane (CH4) exhibits a tetrahedral geometry due to the sp³ hybridization of the carbon atom, which
allows for four equivalent covalent bonds to be formed at approximately 109.5° angles from each
other.

12. What Functional Groups Are Present On This Molecule?

A) Ether And Aldehyde
