1. ENZYMES
Enzymes are the biological
catalysts which speed up the
chemical reaction without
getting consumed.

2. THE REACTION
Enz Product-1 Product-2
Substrate Enzyme
The substrate is broken down into product due to enzymatic
action. . . . Enzyme can be re-used.

3. PROPERTIES OF ENZYMES
They are specific in nature
They are proteins
They have got an optimum temperature
They have got an optimum pH

4. FACTORS AFFECTING THE RATE
OF REACTION
Temperature
Enzyme concentration
Substrate concentration
pH

5. TEMPERATURE AND RATE OF ENZYME
REACTION

6. PH AND RATE OF ENZYME
REACTION

7. SPECIFICITY OF PH FOR AN
ENZYMES

8. ENERGY OF ACTIVATION (PRESENCE & ABSENCE
OF AN ENZYME)
