NEW ACTUAL EXAM WITH
ANSWERS.
Cirrhosis - correct answer -liver becomes so scarred, hardened,
and filled with fat that it loses its function.
liver - correct answer -largest gland,
breaking down fats and toxins
regulate body's blood sugar
make protein for blood clotting. immune function, solute balance
of body fluids.
Energy - correct answer -capacity to do work
light, heat, electricity and motion.
spread out or disperse until no part of a system holds more than
another part.
kinetic energy - correct answer -energy of motion
, Page | 2
Thermodynamics - correct answer -the formal study of heat and
other forms of energy is thermodynamics
first law of thermodynamics - correct answer -the total amount of
energy before and after every conversion is always the same.
Entropy - correct answer -measure of how much the energy of a
particular system has become dispersed.
second law of thermodynamics - correct answer -tendency of
entropy to increase
energy tends to spread out spontaneously
potential energy - correct answer -energy in chemical bond.
energy stored in the position or arrangement of objects in a
system
, Page | 3
Endergonic - correct answer -If the reactants have less free
energy than the products, the reaction will not proceed without a
net energy input.
energy in
Exergonic - correct answer -If the reactants have more free
energy than the products, the reaction will end with a net release
of energy.
energy out
activation energy - correct answer -the minimum amount of
energy required to get a chemical reaction started.
catalysis - correct answer -an enzyme makes a reaction run
much faster than it would on its own.
substrates - correct answer -Of an enzyme, a reactant that is
specifically acted upon by the enzyme.
