enzymes: biological catalysts(unit 3) Flashcards
what is needed for a reaction to occur
particles must collide
particles must have enough energy to react
the energy of the collision depends on the speed of the particles and the angle they collide
the minimum energy needed for them to react is the activation energy
what is a catalyst
a catalyst is a substance that speeds up a reaction
what does the enzyme do
the enzyme lowers the activation energy needed
whats catalytic activity
increase in the rate of a reaction caused by the inclusion of an enzyme
whats a substrate
the molecule that is affected by the action of the enzyme
whats the active site
the area of an enzyme where a substrate binds
whats denatured
when the tertiary structure of the enzyme is changed
how do you measure enzyme reaction
measuring decrease in substrate
measuring increase in product
