Cells must produce many different enzymes because
|
|
enzymes are quickly used up
|
|
|
most cellular reactions require a specific, unique enzyme
|
|
|
They have to have some way to use up the protein that they consume
|
|
|
enzymes are not very effective at speeding up reactions
|
Explanation:
Detailed explanation-1: -Cells must produce many different enzymes because: rate of production of enzymes is important in regulating energy production by cells. enzymes are degraded quickly. most cellular reactions require a specific, unique enzyme.
Detailed explanation-2: -Each enzyme has an “active site.” This area has a unique shape. The substance an enzyme works on is a substrate. The substrate also has a unique shape.
Detailed explanation-3: -Enzymes bind substrates at key locations in their structure called active sites. They are typically highly specific and only bind certain substrates for certain reactions.
