EXAM QUESTIONS
QUESTION 1
carbohydrate
CORRECT ANSWER
biomolecule including sugars and starches
RATIONALE: The term "carbohydrate" specifically refers to a class of biomolecules that include sugars and starches, which
are composed of carbon, hydrogen, and oxygen atoms and are typically found in plants. This definition is based on the
chemical composition and biological origin of these molecules, which distinguishes carbohydrates from other types of
biomolecules.

, QUESTION 2
lipid
CORRECT ANSWER
biomolecule including fats waxes and oils
RATIONALE: The term "lipid" specifically refers to a broad category of biomolecules that include fats, waxes, and oils,
which are characterized by their insolubility in water and ability to release energy when broken down. This classification is
based on the chemical composition and physical properties of these molecules, rather than their specific functions or
sources.
QUESTION 3
protein
CORRECT ANSWER
biomolecule with many different functions depending on shape
RATIONALE: The correct answer is due to the unique characteristic of proteins, which are complex biomolecules composed
of amino acids with their sequence determining the overall shape, or 3D structure, of the molecule. This shape, in turn,
influences the various functions that the protein can perform, enabling it to act as enzymes, hormones, antibodies, or
structural components, among others, making it a molecule with diverse functions dependent on its shape.
QUESTION 4
nucleic acid
CORRECT ANSWER
biomolecule that stores genetic information
RATIONALE: The term "nucleic acid" specifically refers to DNA and RNA, which are molecules composed of nucleotides that
store genetic information essential for the development and functioning of living organisms. This definition is rooted in the
fundamental role nucleic acids play in carrying and transmitting genetic data from one generation to the next.
QUESTION 5
nucleotide
CORRECT ANSWER
monomer of nucleic acids
RATIONALE: A nucleotide is composed of three main components: a phosphate group, a sugar molecule (deoxyribose in
DNA and ribose in RNA), and a nitrogenous base. The term "monomer of nucleic acids" accurately describes a nucleotide's
role as the basic building unit or component that combines with other nucleotides to form nucleic acid polymers, such as
DNA and RNA.

, QUESTION 6
amino acid
CORRECT ANSWER
monomer of protein
RATIONALE: Amino acids are the building blocks of proteins, composed of an amino group and a carboxyl group, with
various side chains that determine their function and properties. The term "monomer of protein" accurately describes amino
acids because they are the individual units that combine through peptide bonds to form larger protein molecules.
QUESTION 7
fatty acid
CORRECT ANSWER
monomer of lipids
RATIONALE: A monomer is a basic building block of a larger molecule, and in the context of lipids, the term "monomer"
refers to the smallest unit that can be combined to form a larger lipid molecule. Fatty acids are indeed the monomers of
lipids because they can be combined through ester linkages to form triglycerides, which are a type of lipid, making fatty
acids the fundamental building blocks of lipids.
QUESTION 8
monosaccharide
CORRECT ANSWER
monomer of a carbohydrate
RATIONALE: A monosaccharide is defined as a simple sugar that cannot be broken down into a simpler sugar by hydrolysis,
which is a characteristic of its monomer status as the smallest unit of a carbohydrate. The prefix "mono-" refers to a single
unit, and saccharide refers to a carbohydrate, making "monomer of a carbohydrate" a synonymous description for a
monosaccharide.
QUESTION 9
short term energy
CORRECT ANSWER
function of carbs
RATIONALE: Carbohydrates serve as the primary source of energy for the body during short-term energy needs because
they can be rapidly broken down into glucose and used by cells to produce ATP through the process of glycolysis. This rapid
energy conversion makes carbs the ideal choice for high-intensity, short-duration activities such as sprinting or weightlifting.

, QUESTION 10
long term energy, insulation
CORRECT ANSWER
function of lipids
RATIONALE: Lipids serve as a long-term energy source due to their high caloric density, allowing them to be stored in the
body as fat and slowly released as energy when needed. Additionally, lipids provide insulation by forming a protective layer
around the body, trapping warm air close to the skin and conserving heat.
QUESTION 11
varied purpose depending on shape
CORRECT ANSWER
function of proteins
RATIONALE: The varied purpose of proteins depending on their shape is due to their unique ability to adopt specific three-
dimensional conformations, which enable them to perform a wide range of biological functions. This shape-shifting ability is
made possible by the complex interactions between amino acids, allowing proteins to bind to specific molecules, catalyze
chemical reactions, and interact with other proteins, ultimately giving them diverse roles in the body.
QUESTION 12
stores genetic material
CORRECT ANSWER
function of nucleic acids
RATIONALE: Nucleic acids, specifically DNA and RNA, serve this purpose due to their unique ability to store and transmit
genetic information through their sequence of nucleotides. This ability is essential for the continuation of life as it allows for
the replication and expression of genes, passing traits from one generation to the next.
QUESTION 13
glucose, fructose, starch
CORRECT ANSWER
carbohydrate molecules
RATIONALE: Glucose, fructose, and starch are all types of carbohydrates, as they are composed of carbon, hydrogen, and
oxygen atoms in various ratios, which is a defining characteristic of carbohydrates. This classification as carbohydrates
allows for the identification of glucose, fructose, and starch as part of a broader chemical category, making "carbohydrate
molecules" a correct description for all three.
