2. Enzymes Flashcards
metabolic pathways are so ___ that we use ___ ___ to analyze these metabolic pathways
complex, computer algorithms
___ ___ is the study of complex systems [in this case metabolisms]
systems biology
___ help organize & regulate these metabolic pathways
enzymes
enzymes are ___ made of ___ ___ that act like a ___/___ in which chemical reactions can occur
catalyst, amino acids , framework/area
catalyst ___/___ rates of chemical reactions/ transformation
increase/ speed up
the enzymes (catalyst) does? or does not? change.
DOES NOT
why do we need chemical reactions to speed up?
a lot of reactions are SLOW
the energy of movement or input of energy is called? include symbol
activation energy (Ea)
activation energy puts reactants (things coming into the enzyme) into what is called?
transition state
the transition state is ___ ___ so in a ____ state
highly reactive , unstable
exergonic ___ energy so ____ energy in products than in reactants so this energy released would be captured by a ____ reaction
releases, less/low, endergonic
activation energy changes the reactants to an ___ , ___ energy form because energy has been added to it called a ___ ___ ___
unstable / high , transition state intermediate
activation energy can come from ___ ___ & ___ ___ ___/___ there by ___ activation energy
increase temperatures & bring reactants , closer/together , lowering
enzymes are __ so they are ___ of ___ ____ that have a ___. ___ ____ which is ____ ____ + ____ _____ ____ then R groups that interact with ____ ___
proteins , chains, amino acids , backbone.
primary sequence , alpha helix, beat pleated sheets, one another
____ are whatever that bind to the enzymes & are involved in chemical reactions [they are reactant]
substrates
enzyme & substrate will come together & the substrate will fit into the enzymes “nook”, which is called?
active site
