all the chemical reactions of life
reactant
what goes into a chemical reaction
product
what is produced from a chemical reaction
catalyst
speed up chemical reactions
protein
enzymes are what type of biomolecule
lowering the activation energy
How do enzymes speed up reactions?
active site
the specific shape that determines an enzymes job
substrate
what is changed by the enzyme
enzyme-substrate complex
the precise fit between the substrate and the enzymes active site, similar to a lock and key (the reaction occurs here)
shape (active site)
what determines if an enzyme can catalyze a reaction
shape
an enzyme can be used over and over again as long as it keeps it _____
denatured
when an enzyme’s shape changes
inhibit
to stop, prevent, hinder
enzymes
end in -ase (example: lactase)
sugars
end in -ose (example: Lactose)
competitive inhibitor
directly blocks active site and reaction cannot occur
non-competitive inhibitor
changes the shape of the active site and reaction cannot occur
7
what is the optimum pH of enzyme A
37
what is the optimum temperature for enzyme A
the activation energy needed to start the reaction with an enzyme
what does A represent
the temperature was too high and denatured the enzyme
why does the reaction immediately fall and then stop after 60 degrees?
