5.1 Study guide Flashcards
Enzyme
catalysts
reaction specific
made of protien
Catalyst
Speed up chemical reactions
Chemical reaction
A process in which 1 or more substances are converted to 1 or more substances
Activation Energy
The minimum quantity needed to undergo a reaction
Substrate
Reactant which binds to enzyme
Active site
Where substrate fits into enzyme
Enzymes will usually either preform
hydrolysis or dehydration synthesis
Properties of enzymes
Reaction specific
-each enzyme= specific substrate
Not consumed in reaction
-single enzyme= lots of reactions
Made of proteins (Sometimes RNA)
Affected by cellular conditions
-denatured by certain temperatures or concentrations of ions. (PH, salinity)
Hydrolysis (how I understand)
1 = 2
Dehydration synthesis
(remove water)
2 = 1
Enzymes concentration
increased reaction rate
increased enzyme concentration
substrate concentration
increased reaction rate
increased substrate concentration
middle temp
highest reaction rate
middle PH
highest reaction rate
inhibition
rate of enzyme reaction is reduced
