enzymes and proteins

Question 1

What is the general properties of enzymes ?

Answer 1

Higher reaction rates
106 to 1012 times faster than uncatalyzed, 103 x chemical

Milder reaction conditions
Below 100°C, atmospheric pressure, neutral pH
Compare to Haber nitrogen fixation, ester hydrolysis

Greater reaction specificity
Rare to have side products
Stereospecificity

Capacity for regulation

Question 2

How do enzymes work ?

Answer 2

v proportional to enzyme conc however saturation kinetics -at high (S),v no longer rises
