Metabolism Exam Questions with Correct Answers Fully Solved
Metabolism - Answers Totality of an organisms chemical reactions (manages materials and energy
resources of a cell)
Catabolic Pathways - Answers Release energy by breaking down complex molecules into simpler
compounds (digestive enzymes breakdown food
Anabolic Pathways - Answers Consume energy to build complex molecules and rebuild proteins
Dehydration Synthesis - Answers Taking away water in order to create a new compound
Hydrolysis - Answers Adding water to break one compound into two
Energy - Answers Capacity to do work
Kinetic Energy - Answers Energy associated with motion
Thermal (Heat) Energy - Answers Kinetic energy associated with random atomic motion
Potential Energy - Answers Stored energy relative to position
Chemical Potential Energy - Answers Energy available for release in chemical reactions
Thermodynamics - Answers Study of energy transfers that occur in nature
Closed System - Answers A system isolated from any outer surroundings
Open System - Answers Energy and matter can be transferred with surroundings (organisms)
1st Law of Thermodynamics - Answers Energy cannot be created or destroyed, only transferred
2nd Law of Thermodynamics - Answers Every energy transfer adds to the entropy (chaos) of the
universe (some unusable energy is lost as heat, which contributes to entropy
Free Energy (G) - Answers Part of a system's energy that can perform work.
Equilibrium - Answers When G is at absolute minimum. The higher the G, the lower the stability
Delta (Change in) G - Answers Negative: Energy is lost (greater stability)
Positive: Not spontaneous
Catabolism - Answers Releases energy, hydrolysis, digests polymers
Anabolism - Answers Puts energy into a reaction, dehydration synthesis, build polymers
Exergonic Reaction - Answers Energy is lost, and used in digestion and catabolism
