Cleveland State Biology 200 Exam 2
Q&A
delta G - ANSWER-delta h - T delta S
delta - ANSWER-change in value after reaction (F - I)
H - ANSWER-enthalpy (total energy)
T - ANSWER-temp ( Kelvin)
spontaneous processes have a - ANSWER-negative delta Gs
positive delta G require - ANSWER-energy input
Exergonic - ANSWER-more energy in reactants and less in products
endergonic - ANSWER-less energy in reactant and more in products
activation energy - ANSWER-Free energy of activation is the energy needed to start
a reaction
enzymes catalyze biochemical reactions and - ANSWER-orient substrates; strain
bonds in substrate; create favorable micro environment (ph) ; May briefly bond
covalently to substrate
active site - ANSWER-induced fit, enzyme changes shape after substrate binds
enzymes are specific for - ANSWER-particular substrates
enzymes change shape when substrates - ANSWER-bind
enzymes are not changed by - ANSWER-reaction
cofactors - ANSWER-non protein enzyme helpers usually inorganic
coenzyme - ANSWER-non protein, organic molecules ; often carrier or transport
molecules Vitamins or derived from vitamins
enzyme activity - ANSWER-allosteric reactions ; not the active site
regulating enzyme activity - ANSWER-competitive inhibition
inhibitor binds to - ANSWER-active site and prevents substrate from binding
