ve Site Models
27) In the active site, there are two models of substrate binding. What is described in the lock-
and-key model?
28) What is does the 'induced-fit' model account for?
Temperature Effect
29) Why are most enzyme inactive at higher temperature (greater than 37-degrees Celsius)?
30) Does this happen to all enzymes in all species?
31) There are several modes for enzyme regulation. What's the difference between competitive
and non-competitive inhibition? (It may be helpful to diagram this.)
Enzyme Co-factors
32) NAD+ and FAD are essential cofactors for biological redox reactions. When they gain
electrons (and hydrogens) are they oxidized or reduced?
33) What are the formulas for the reduced forms of the coenzymes?
