Question

Which things are expected to INCREASE the rate of an enzymatic reaction? Check all that apply ->

Answer 1

Add my enzyme, add more substrate and adjust pH to optimal level will all increase the rate of a reaction. Freezing or too low of temperatures will make most enzymes unable to work.
The first three are correct.

Answer 2

Adding more enzyme, adding more substrate and adjusting the pH to an optimum level

Step-by-step explanation:

-Add more enzyme:

This would allow for more conversions to happen quicker, as the more enzymes there are, the more active sites are open to allow for the enzymatic reaction to take place.

-Add more substrate:

Although adding more substrate will allow for any enzymes not already catalysing at its maximum capacity, to convert more substrate, there is an upper limit known as the V max. This is the limit of how much substrate can be converted at a time, so once V max is reached, the reaction will not take place an faster.

-Adjust the pH to optimal level:

When the pH of a solution changes, it affects the enzymes and proteins within the solution. Hence, if the pH is adjusted to allow the enzyme to catalyse substrate more effectively, that will increase the rate of reaction.

-Freezing the enzyme:

This option would not increase the rate of reaction. When enzymes are frozen, they become inactive, meaning they cannot catalyse a reaction.
