potential energy stored energy (chemical bonds, concentration gradients, electrical
potential)
kinetic energy movement energy (Heat=molecular motion, mechanical=moving
molecules past each other, electrical=moving charged particles)
Law of Conservation of Energy Energy cannot be created or destroyed, can be
transformed from one type to another, most of the energy for life comes from sun, living
organisms capture-convert-store energy
second law of energy transfer or transformation of energy increases disorder of a system
∆G change in free energy
∆G=∆H-T∆S the change in free energy during a process is related to the change in
enthalpy, or change in total energy, change in entropy, and temperature in Kelvin

100% Solved
∆G that's less than zero spontaneous, reaction is exergonic
exergonic releases energy
∆G that's greater than zero non-spontaneous, reaction is endergonic
endergonic requires energy
∆G that is zero in equilibrium, no change
stored chemical energy must be released, process that release energy lead to ATP
synthesis and are catabolic/exergonic
movement requires energy, processes that require energy lead to ATP consumption and
are anabolic/endergonic

ATP (adenosine triphosphate) main energy source that cells use for most of their work,
not the highest energy molecule
high energy phosphate bond in ATP is easy to break and requires energy
ATP hydrolysis releases energy into the environment and can fuel the needs of other
reactions
ATP phosphorylation increases energy of other molecules
phosphorylation The metabolic process of introducing a phosphate group into an organic
molecule.
How is ATP generated by the phosphorylation of ADP in a metabolic pathway
metabolic pathway the product of one reaction is is the reactant for the next
