Studied by 14 peopleactivation energy
energy required to start a reaction
active site
site on enzyme where reaction occurs
allosteric inhibition
inhibits enzyme reactions by binding to a site OTHER than the active site
anabolic
reaction uses energy to build up molecules, dehydration reaction, water is reactant
ATP
Adenosine Triphosphate, energy of cell, drives cellular work
bioenergetics
the study of how living organisms convert and utilize energy.
catabolic
releases energy by breaking up molecules, hydrolysis, water is product
chemical energy
potential energy within a bond, released by breaking bond
coenzyme
organic molecules that assist enzyme
cofactor
inorganic molecules that assist enzyme
competitives inhibition
inhibits enzyme reactions by binding to the active site and prevents substrates from binding there
denature
when pH,temperature, chemicals in environment cause a protein to lose shape and therefore be unable to function
endergonic
requires energy
exergonic
releases energy
enthalpy
net change in heat (ΔH)
entropy
disorder, chaos (ΔS)
induced fit
molecular handshake - when enzyme binds to substrate by changing shape around substrate
kinetic energy
energy associated with motion
substrate
components of reaction that bind to the active site
First Law of Thermodynamics
Energy cannot be created or destroyed
Second Law of Thermodynamics
entropy of the universe as a system is always increasing
