Exam Questions and CORRECT Answers
Metabolism - CORRECT ANSWER - the totality of an organism's chemical reactions
Metabolic Pathway - CORRECT ANSWER - begins with a specific molecule which is then
altered through a series of defined steps to create a product
Metabolism manages _________ _________ resources of the cell - CORRECT ANSWER -
material and energy
catabolic pathways - CORRECT ANSWER - release energy by breaking down complex
molecules into simpler compounds
anabolic pathways - CORRECT ANSWER - consume energy to build complex molecules
from simpler ones
Example of anabolic pathway - CORRECT ANSWER - synthesis of protein from amino acids
example of catabolic pathway - CORRECT ANSWER - Cellular respiration, the breakdown
of glucose in the presence of oxygen
Energy - CORRECT ANSWER - The ability to do work or cause change
Kinetic energy - CORRECT ANSWER - energy of motion
Potential energy - CORRECT ANSWER - stored energy
, Chemical energy - CORRECT ANSWER - A form of potential energy that is stored in
chemical bonds between atoms
Glucose is _______ in chemical energy - CORRECT ANSWER - high
Thermodynamics - CORRECT ANSWER - study of the flow and transformation of energy in
the universe
first law of thermodynamics - CORRECT ANSWER - Energy can be transferred and
transformed, but it cannot be created or destroyed
second law of thermodynamics - CORRECT ANSWER - Every energy transfer or
transformation increases the entropy of the universe.
Entropy - CORRECT ANSWER - A measure of disorder or randomness.
spontaneous process - CORRECT ANSWER - a process that can occur without an input of
energy

Equilibrium - CORRECT ANSWER - A state of balance
When a reaction proceeds towards equilibrium, the free energy of the mixture of reactants and
products ___________ - CORRECT ANSWER - decreases
Exergonic - CORRECT ANSWER - Chemical reactions that release energy
