BIO 1201 GREGG EXAM 2 FINAL SCRIPT
2026 COMPLETE QUESTIONS AND
ANSWERS PACKAGE
◉ What is energy coupling?.
Answer: using energy released from exergonic reactions to drive
endergonic reactions
◉ Metabolism.
Answer: Totality of organisms chemical reaction
◉ Metabolic pathway.
Answer: begins with a specific molecule and ends with a product
◉ Distinguish types of energy with diving example. Remember its a
cycle.
Answer: Standing on diving board- potential
Diving- potential to kinetic
Climbing back up- kinetic to potential
◉ first law of thermodynamics.
, Answer: Energy can be transferred and transformed, but it cannot
be created or destroyed.
◉ second law of thermodynamics.
Answer: During energy transfer, some is lost as heat. When you
convert energy, some of useful energy decreases
◉ Describe free energy.
Answer: energy available to an organism for work
less free energy: more stable, less work
More free energy: less stable, greater work
◉ Spontaneous reaction.
Answer: Release free energy (exergonic) system is now more stable
◉ Non spontaneous reaction.
Answer: Requires free energy (endergonic)
◉ What is more likely to produce a spontaneous reaction?.
Answer: Negative enthalpy and pos energy
◉ What is a catalyst?.
