Introduction of Enzymes Flashcards
Enzymes
biological catalysts
Enzymes are responsible for
supporting (almost) all chemical reactions that maintain biological homeostasis
Enzymes also increase
the rate of reaction
Types of Catalysts
Organic and Biological
Enzymes Location (2)
Extracellular and Intracellular
Integral vs Peripheral
part of the membrane
vs.
Associate/dissociate with the cell
Enzyme classes
Absolutely specific
Group specific
Linkage specific
Sterochemically specific
Oxidoreductase
catalyze a redox reaction
Transferase
transfer a functional group
Hydrolase
causes hydrolysis (breakdown in the present of water) reaction
Lyase
Break C-O, C-C, or C-N bonds
Isomerases
rearrange functional groups (isomerization)
Ligase
Join two molecules
Equilibrium means
no net change/no change in concentration
High equilibrium constant means
a lot of the reactants become products before reaching equilibrium
