A+ GRADED| BRAND NEW RELEASE!
This comprehensive examination bank is designed for students enrolled in BIOD 101:
Essential Biology I with Lab through Portage Learning. The content covers all six
modules of the course, providing complete verified questions, correct answers, and
detailed rationales for each topic.
The examination assesses a student's understanding of foundational biology concepts
including the chemistry of life, cell structure and function, metabolism and energy,
genetics and DNA, evolution and diversity, and microbiology and immune responses.
EXAMINATION DOMAINS :
1. Module 1: Chemistry of Life and Macromolecules
2. Module 2: Cell Structure and Function
3. Module 3: Metabolism and Energy
4. Module 4: Genetics and DNA
5. Module 5: Cellular Signaling
6. Module 6: Microbiology and Immune Responses
7. Final Exam: Comprehensive
,BIOD 101 MODULE 1 EXAM
Chemistry of Life and Macromolecules (Questions 1–45)
1. True or False; If false, make the statement true: Passive transport is vital for
moving essential nutrients into the cell. Should passive transport stop, the cell would
cease to function.
Answer: False. Active Transport is vital for moving essential nutrients into the cell.
Should active transport stop, the cell would cease to function.
Rationale: Active transport uses energy (ATP) to move molecules against their
concentration gradient, which is essential for nutrient uptake and cell survival.
Passive transport does not require energy.
2. What is/are a type of organic compound that biomacromolecules are comprised
of?
Answer: Carbohydrates, Nucleic Acids, Lipids, Proteins.
Rationale: The four major classes of biological macromolecules are
carbohydrates, lipids, proteins, and nucleic acids.
3. Matter can exist in which of the following states:
Answer: Gaseous, Solid, Liquid.
, Rationale: Matter commonly exists in three states: solid, liquid, and gas.
4. Amino Acids that must be obtained from food in the diet / cannot be
manufactured by the human body are known as _____ while amino acids that are
able to be manufactured by the human body are known as _____.
Answer: Essential; Non-essential
Rationale: Essential amino acids must be obtained from the diet, while non-
essential amino acids can be synthesized by the body.
5. What type of Ion carries a negative charge?
Answer: Anion
Rationale: An anion is a negatively charged ion (gained electrons). A cation is
positively charged (lost electrons).
6. Which Organelle contains the genomic content of the cell whilst serving as the
control center?
Answer: Nucleus
Rationale: The nucleus contains the cell's DNA (genomic content) and serves as the
control center for cellular activities.
, 7. What type of cell junctions are tiny pores or channels that allow for the passage
of substances from cell to cell?
Answer: Gap Junctions
Rationale: Gap junctions are channels between adjacent cells that allow ions,
nutrients, and signaling molecules to pass directly from one cell to another.
8. Name the 3 parts of a nucleotide
Answer: 1. A Phosphate group, 2. A 5-carbon sugar (deoxyribose in DNA or
ribose in RNA), 3. A Nitrogen-containing ring called a nitrogenous base.
Rationale: Nucleotides, the monomers of nucleic acids, are composed of a
phosphate group, a pentose sugar, and a nitrogenous base.
9. Indicate which statements are True & which are False concerning Eukaryotic cells
Answer:
a. Eukaryotic cells are less complex than prokaryotic cells (False)
b. Eukaryotic cells possess a nuclear membrane (True)
c. Eukaryotic cells contain membrane-bound organelles (True)
d. Eukaryotic cells are larger than prokaryotic cells (True)
