UPDATED ACTUAL Exam Questions and
CORRECT Answers
Metabolism - CORRECT ANSWER - All of the chemical reactions that occur within an
organism
metabolic pathway - CORRECT ANSWER - A series of chemical reactions that either builds a
complex molecule or breaks down a complex molecule into simpler compounds.
metabolic pathway example - CORRECT ANSWER - substrate --> intermediate -->
intermediate --> product
Two types of metabolic pathways - CORRECT ANSWER - catabolic and anabolic
catabolic pathways - CORRECT ANSWER - pathways that release energy by breaking down
complex molecules into simpler compounds
anabolic pathways - CORRECT ANSWER - pathways that consume energy to build
complicated molecules from simpler compounds
energy - CORRECT ANSWER - the ability to do work
organisms need energy to ______ and ________ - CORRECT ANSWER - survive and
function
a loss in energy flow results in _________ - CORRECT ANSWER - death
kinetic energy - CORRECT ANSWER - energy associated with motion
, thermal energy - CORRECT ANSWER - energy associated with the movement of atoms or
molecules
potential energy - CORRECT ANSWER - stored energy
chemical energy - CORRECT ANSWER - potential energy available for release in a chemical
reaction
How does a surfer represent the forms of energy? - CORRECT ANSWER - -Surfer being
lifted in the waves is potential
-Surfer riding the wave is kinetic
Thermodynamics - CORRECT ANSWER - the study of energy transformations in matter
the laws of thermodynamics apply to - CORRECT ANSWER - the universe as a whole
first law of thermodynamics - CORRECT ANSWER - energy can be transferred or
transformed, but it cannot be created or destroyed
How does a squirrel eating a nut and climbing a tree represent thermodynamics? - CORRECT
ANSWER - The chemical (potential) energy stored in the nut will be transformed into kinetic
energy for the squirrel to climb the tree
second law of thermodynamics - CORRECT ANSWER - -Energy transformation increases the
entropy (disorder) of the universe
-During energy transfers of transformations, some energy is unusable and often lost as heat
Cells create organized structures by taking in less organized starting materials. If this is true, how
do cells not violate the 2nd law of thermodynamics? - CORRECT ANSWER - Catabolic
