AP Biology Unit 3 Review

Where on an enzyme does the substrate bind?

• active site

• allosteric site

• C-terminus

• N-terminus

Which environmental conditions can cause denaturation of the enzyme?

• slight increase in temperature

• extreme increase in temperature

• decrease in temperature

• extreme increase in temperature and pH changes

Describe why an increase in temperature increases the rate of the reaction.

• increase in temperature increases the speed/kinetic energy of particles

• increase in temperature activates more enzyme to increase the rate

• increase in temperature results in increase in substrate available

• increase in temperature allows for a tighter fit in the active site
