CHAPTER 1: Biochemistry and the Organization of Cells
Multiple Choice Questions
1. Which of the following elements makes up the largest percentage of the human body by mass?
A) Carbon
B) Hydrogen
C) Oxygen
D) Nitrogen
Answer: C
Explanation: Oxygen constitutes approximately 65% of the human body by mass, largely because of the
abundance of water.
2. Which level of protein structure is most directly determined by the amino acid sequence?
A) Primary structure
B) Secondary structure
C) Tertiary structure
D) Quaternary structure
Answer: A
Explanation: Primary structure refers to the linear sequence of amino acids in a polypeptide chain,
which is directly encoded by the gene.
3. The fluid mosaic model of membrane structure was proposed by:
A) Watson and Crick
B) Singer and Nicolson
C) Lehninger and Nelson
D) Pauling and Corey
Answer: B
Explanation: Singer and Nicolson proposed the fluid mosaic model in 1972, describing the cell
membrane as a dynamic structure with proteins embedded in a fluid lipid bilayer.
, 4. Which of the following is NOT a characteristic of living organisms?
A) Ability to replicate
B) Capacity to respond to stimuli
C) Crystalline internal organization
D) Ability to extract energy from surroundings
Answer: C
Explanation: Living organisms are characterized by complex, non-crystalline internal organization.
Crystalline structures are typically associated with non-living matter.
5. Prokaryotic cells differ from eukaryotic cells in that prokaryotes:
A) Lack ribosomes
B) Lack a membrane-bound nucleus
C) Cannot carry out transcription
D) Do not contain DNA
Answer: B
Explanation: Prokaryotes lack a membrane-bound nucleus; their DNA is located in a nucleoid region.
They do have ribosomes and carry out transcription and translation.
6. Which organelle is responsible for oxidative phosphorylation in eukaryotic cells?
A) Endoplasmic reticulum
B) Golgi apparatus
C) Mitochondrion
D) Lysosome
Answer: C
Explanation: Mitochondria are the site of oxidative phosphorylation, where the electron transport chain
and ATP synthase produce the majority of cellular ATP.
7. Which of the following biomolecules serves as the primary long-term energy storage in animals?
A) Glycogen
B) Starch
C) Triacylglycerols (fats)
D) Proteins
Answer: C
Explanation: Triacylglycerols are the primary long-term energy storage molecules in animals due to their
high energy density and hydrophobic nature.
8. The endosymbiotic theory proposes that mitochondria originated from:
A) Invaginations of the plasma membrane
