What is an exchange reaction? - correct
answer=✔✔A chemical reaction that
involves both synthesis and
decomposition.
1
,Why is kinetic energy relevant to
atoms? - correct answer=✔✔All atoms
are in constant motion, and the speed
of this motion determines their kinetic
energy.
What is an electrolyte? - correct
answer=✔✔A soluble, inorganic
compound that dissociates into
cations and anions to conduct
electricity in solution.
Why is water considered the universal
solvent in the body? - correct
answer=✔✔Its polarity allows it to easily
dissolve ionic and polar organic
substances.
2
,What distinguishes hydrophobic
substances from hydrophilic ones? -
correct answer=✔✔Hydrophobic
substances are nonpolar and do not
dissolve in water, while hydrophilic
substances are polar and associate
with water molecules.
What are the four main categories of
organic compounds in the body? -
correct answer=✔✔Carbohydrates,
proteins, lipids, and nucleic acids.
What is the primary function of
carbohydrates in the body? - correct
answer=✔✔To serve as the main source
of energy for release and storage.
3
, What is the storage form of glucose in
the liver and muscles? - correct
answer=✔✔Glycogen.
How do lipids travel through the
bloodstream? - correct answer=✔✔They
use special transport mechanisms
called lipoproteins.
What are the three main types of
lipids? - correct
answer=✔✔Triglycerides,
phospholipids, and steroids.
What is the structural role of
phospholipids? - correct
answer=✔✔They form the lipid bilayer
of cell membranes.
