Enzyme Activity.

There are 4 conditions which affect enzyme activity: Temperature, 'p' 'H', Enzyme concentration and substrate concentration.

Temperature:

• When the temperature increases the Kinetic energy increases so the molecules move faster.
• As the molecules have a higher Kinetic energy meaning that there are more collisions per second.
• As the temperature increases meaning that the energy of the collisions so it is more likely to result in a reaction.
• However as the temperature rises so does the vibration of the enzymes.
• When the temperature goes above the Optimum Temperature bonds begin to break within the enzyme.
• The active site changes shape (denatures) so the enzyme-substrate cannot form.

'p' 'H':

• Above 7 there are Hydroxyl Ions present.
• Below 7 there are Hydrogen ions present.
• These alter the charge distribution which changes the active site.

Enzyme Concentration:

• More enzymes molecules there are in solution then the chance of collisions resulting in the enzyme-substrate complex. So by increasing the concentration of enzyme increases the rate of reaction.
• If substrate concentration is limited an increase in enzyme concentration will eventually have no effect.

Substrate Concentration:

• The higher the…
