Factors Affecting Enzyme Activity

QuestionAnswer
Enzymes are ......... by ............... and have a ........ in which they ......... most ...........? Enzymes are affected by temperature and have a range in which they function most efficiently.
What is this range called? The optimum range
Below this range they function ...... ............? Below this range they function less efficiently.
Above this range, they are .............? Above this range, they are denatured.
Enzymes are ............ to .....? Enzymes are sensitive to pH.
Every enzyme has its own ......... of ....., in which it .............. .......? Every enzyme has its own range of pH, in which it functions best.
Most ............... enzymes ............... ....... at around ........ (pH...). Most intracellular enzymes function best at around neutral (pH7).
............ acidity (pH ........ ..... ..) or .......... (pH ........ ....... ...) ........... them and makes them ........? Excessive acidity (pH less than 7) or alkalinity (pH more than 7) denatures them and makes them inactive.
Not all ......... ............. ....... in a ........... environment Not all enzymes function best in a neutral environement.
The amount of ........... or .......... in a reaction can ...... the amount of ........ ........... The amount of substrate or enzyme in a reaction can limit the amount of product produced.
Increased amounts of ......... will result in more ......... being made until all the ......... molecules are ........... at their ................. capacity. Increased amounts of substrate will result in more products being made until all the enzyme molecules are working at their maximum capacity.
At a given concentration of .........., if the ........ .................. increases, the ....... of ........... ............ The final .......... of .......... does not ......., only the ....... at which it is ............. At a given concentration of substrate, if the enzyme concentration increases, the rate of reaction increases. The final amount of product does not differ, only the speed at which it is produced.
What does increasing enzymes do? speeds up the reaction but not the amount of product produced.
What does increasing the amount of substrate do? Increases the amount of product produced but does not speed up the rate of reaction
