Unit 2: ENZYMES AND ENZYME ACTIVITY

These consist of helix and pleated sheets.



















Changes to Enzyme Activity

Temperature and Enzymes

The optimum temperature is the temperature which
the greatest and fastest enzyme activity occurs.
Above this temperature, the enzyme denatures and
ceases to function.

PH and Enzymes

The optimum pH level is dependent upon the
enzyme. Above the given optimum pH, the
enzymes denature.











Substrate Concentration and Enzyme Activity

The more substrate you add to the
enzyme, the faster the rate of reaction until
all the active sites are being used. Hence
the flat…
