Question | Answer |
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 |
