,1. Multiple Choice: Which of the following is a primary
function of carbohydrates in organisms?
A) Energy storage
B) Catalyzing biochemical reactions
C) Structural support
D) Insulation and protection
Answer: A) Energy storage
Rationale: Carbohydrates are primarily used by
organisms to store and provide energy, particularly in the
form of glucose.
2. Fill-in-the-Blank: The type of isomerism caused by the
presence of a different functional group is called ________
isomerism.
Answer: Functional
Rationale: Functional isomerism occurs when two or more
compounds have the same molecular formula but different
functional groups.
3. True/False: Enantiomers are mirror images of each other
and are non-superimposable.
Answer: True
Rationale: Enantiomers are a type of stereoisomer where
the molecules are non-superimposable mirror images of
each other, often resulting in different biological activities.
4. Multiple Response: Select all that apply. Which of the
following are properties of lipids?
A) Soluble in water
B) Energy storage
©2024/2025
, C) Insoluble in organic solvents
D) Structural components of cell membranes
Answers: B) Energy storage, D) Structural components of
cell membranes
Rationale: Lipids are known for energy storage and being
structural components of cell membranes. They are
insoluble in water but soluble in organic solvents.
5. Multiple Choice: What is the product of the reaction
between an acid and an alcohol?
A) Ketone
B) Ester
C) Amide
D) Ether
Answer: B) Ester
Rationale: The reaction between an acid and an alcohol
typically forms an ester and water in a process known as
esterification.
6. Fill-in-the-Blank: Proteins are polymers of ________
acids.
Answer: Amino
Rationale: Proteins are made up of long chains of amino
acids, which are the building blocks of proteins.
7. True/False: The pH scale is a measure of the
concentration of hydroxide ions in a solution.
Answer: False
Rationale: The pH scale actually measures the
concentration of hydrogen ions in a solution, with lower pH
values indicating higher acidity.
8. Multiple Response: Which of the following are considered
