Chapter 4 Powerpoint Flashcards
Proteins that catalyze (speed up) reaction rates
Enzymes
named for the reaction that catalyze and their names end in the suffix -ase.
Enzymes
what breaks down the sugar sucrose
SucrASE
The energy required to start the metabolic reaction serves as a barrier to catalysis
Activation Energy
The amount of _____ ______ required is decreased by enzymes.
Activation Energy
The chemicals that are metabolized by an enzyme-catalyzed reaction are called the enzymes
substrate
The region of the enzyme where the substrate binds is called the enzymes
Active Site
Enzyme changes shape after substrate binds, which stresses the substrate bonds.
True
Shape change by the enzyme in response ti substrate binding results in stress being placed on the bonds of the substrate than alters the substrate.
Induced Fit
Each enzyme catalyzes a particular reaction
specificity
The _______ of an enzyme is the result of its shape and the shape of its active site.
Specificity
Each enzyme catalyzes a particular reaction based on enzyme shape and active site shape.
true
Each enzyme is composed of varying sequences of _____ ______.
amino acids
____ determine the specific enzyme protein.
Genes
Enzymes are proteins that _____, or speed up, chemical processes
catalyze
