Important Concepts

Minimal enzyme activity

not permanent state, can be restored once temperature rises

Occurs a high temperature and high pH

Irreversible damage to specific 3D shape

Results in no longer being able to catalyse reactions

Rate of enzyme acitivy depends on kinetic energy of molecules

Rise in temperature

Results in kinetic energy of molecules

Results in rise in collisions between enzyme & substrate molecules

Results in rise in ezyme activity

Changes in pH slightly decreases enzyme acitity but not permanent state

Extreme pH values will irreversible denature enzymes

At pH 4 & 9, enzyme is completely denatured

At medium becomes more acidic or akaline, enzyme activity decreases

Alters the rate of chemical reactions in cells

Remains the same at the end of the reactions

Are mainly proteins

Highly specific in action

Required in minute amounts
