BIOLOGY EXAM 2 STUDY GUIDE 2026/2027
energy - ANS ✔✔the capacity to do work
work - ANS ✔✔the transfer of energy to an object causing the object to move
potential energy - ANS ✔✔stored energy (position)
kinetic energy - ANS ✔✔energy of movement (motion)
law of conservation of energy - ANS ✔✔energy can neither be created nor destroyed
second law of thermodynamics - ANS ✔✔energy conversions result in a loss of useful energy
entropy - ANS ✔✔amount of randomness and disorder in a system
endergonic reaction - ANS ✔✔require an outside energy contribution before it can take place; net input
of energy
exergonic reaction - ANS ✔✔occur spontaneously without having to input energy; release energy
activation energy - ANS ✔✔the energy needed to begin chemical reaction
ATP - ANS ✔✔short term energy storage
coupled reactions - ANS ✔✔exergonic reaction creates energy to start endergonic reaction
catalyst - ANS ✔✔reduce the energy required to start a reaction; lowers activation energy
enzymes - ANS ✔✔specific proteins that catalyze specific reactions
competitive inhibitor - ANS ✔✔a molecule that occupies the active site and blocks the entry of the
substrate
noncompetitive inhibitor - ANS ✔✔causes the active site to change shape so the substrate no longer fits
affects enzymes - ANS ✔✔temperature, ph, and salt concentration
glucose breakdown - ANS ✔✔C6H12O6 + 6O2 --> 6CO2 + 6 H2O + ATP energy + heat energy
photosynthesis - ANS ✔✔6CO2 + 6H2O + light energy --> C6H12O6 + 6O2
glycolysis - ANS ✔✔splits apart glucose into two molecules of pyruvate
