The first one, Added removed or changed. Mutation as in anything that would cause the slightest change.
From the options that factor that does not effect the rate of enzyme reaction is : ( D ) Amount of product.
Enzymes are substances found in organisms that catalyzes the rate of chemical reaction occurring in an organism. during the chemical reaction the enzyme remains intact and is not utilized during the process.
Some of the process that may Inhibit the performance of an enzyme(s) includes ;
- pH ,
- The substrate concentration,
- Temperature and
- The concentration of the enzyme.
The amount of the product does not affect the performance rate of the enzyme because enzymes functions in chemical reactions and not physical reactions
Hence we can conclude that the factor that does not effect the rate of enzyme reaction is the Amount of product
