Bio 411 Exam 2 Questions with Answers (100% Correct
Answers)
Bioluminescence Answer: Conversion of energy to light
Metabolism Answer: The totality of an organism's chemical reactions
Metabolic pathway Answer: A series of chemical reactions that either
builds a complex molecule or breaks down a complex molecule into
simpler compounds.

Anabolic pathways Answer: Called bio synthetic pathways, consume
energy to build complex molecules from simpler ones
Energy Answer: the capacity to cause change - perform work
Work Answer: Movement of matter
Kinetic energy Answer: Energy associated with motion
Thermal energy Answer: Kinetic energy associated with random
movement of atoms or molecules
Heat Answer: Thermal energy in transfer from one object to another
Light energy Answer: Can be harnessed to perform work
Potential energy Answer: Energy that matter possesses because of its
location or structure
Chemical energy Answer: Potential energy available for release in
chemical reaction
Energy Answer: ______ can be converted from one form to another
Thermodynamics Answer: The study of energy transformations

Open systems Answer: Energy and matter can be transferred between
the system and its surroundings in ____ _____.
Isolated system Answer: Exchange with the surrounds cannot occur
Open Answer: organsims are ____ systems
first law of thermodynamics (law of conservation of energy) Answer:
Energy can be transferred and transformed, but it cannot be created or
destroyed.
second law of thermodynamics Answer: Every energy transfer or
transformation increases the entropy of the universe.
Entropy Answer: A measure of molecular disorder or randomness.
Disorder Answer: How dispersed energy is in a system and how many
energy levels are present
why does every transfer or transformation of energy increase entropy
Answer: Some energy is lost to the surroundings as heat and heat
increases the disorder of the surroundings
Spontaneous processes: Answer: Release energy
