AP Bio enzyme Lab exam questions and
answers
High temp ANSWERS Warm temp to a certain extent can speed up the reaction
but once the temp gets to high the . enzymes denature at a high temp which break the
weak bonds that hold the 3rd structure together
In order to effectively initiate a reaction, collisions must be sufficiently energetic (kinetic
energy) to break chemical bonds; this energy is known as the activation energy.
As the temperature rises, molecules move faster and collide more vigorously, greatly
increasing the likelihood of bond breakage upon collision.
relationship between product and time ANSWERS the reaction rate goes up at a
constant slope because the enymes are working as fast as they can but then the line
goes flat because because there is no more product to be made because the substrates
are used up
relationship between reaction rate and ANSWERS the line goes up because the
reaction rate is getting higher and higher and than it goes at a constant speed because
the enzymes are working as fast as they can and then it goes down because the
substrates are being used up so the enzymes dont have to work as hard collision rate
goes down
low temp ANSWERS rate of reaction decreases with a lower temp because the
kentic energy of the particles go down in the collision theory decreases. affecting the
collision theory
pH ANSWERS pH can affect the structure because the h+ or OH- ions can
interact with the polar or charged R groups which cause a denaturation of the enymes
Salinity ANSWERS turnips prefer a salty environment, certain enzymes prefer
salty environments. Rate of reaction is higher with salt. Not all enzymes prefer a perfect
environment. But if they do the salt ions interact with the polar and charged R groups
making active site denature
substrate concentration ANSWERS the lower the concetration of the substrate the
less substrate there is for the collision theory, less substrate less things to bond to
active site
metal Ion concentration ANSWERS Cu+2 ions (or metal ions) inhibit the power of
enzymes because they interact with charged R groups to denature enzymes.
