Enzymes

Question 1

What factors affect the rate of an enzyme catalyzed rxn?

Answer 1

-increasing temp, concentration

Question 2

What are enzymes? Why are they important ?

Answer 2

• biological catalysts that speed up rxn rate without being consumed
• reactions in the body would take too long

Question 3

How does temperature affect rxn rate?

Answer 3

When there is an increase in temperature the reaction rate also increases as it reaches optimal temperature

Question 4

Compare and contract competitive vs non competitive inhibitors

Answer 4

Competitive:
-molecules resembles active site, blocks access of normal substrate = rxn rate slows down

Non-competitive (allosteric):

• binds to enzyme outside of active site - changes enzyme shape
• regulatory molecule prevents substrate from binding to active site

Question 5

Describe an experiment that tests whether a chemical is competitive inhibitor or a non competitive inhibitor

Answer 5

Increase the amount of normal substrate, if reaction rate increases it is a competitive inhibitor
