Question

Jacob argued that enzymes are not reusable and function to slow down the rate of reactions.

Which statements show why Jacob's argument is incorrect? Select all that apply.

A
Enzymes are catalysts that speed up chemical reactions.

B
Enzymes increase the activation energy that is required for chemical reactions.

C
Enzymes are changed by the reaction and can be reused.

D
Enzymes are specific to the substrate to which they bind and can be reused.

E
All enzymes act on different reactions and by increasing the rate of the reaction.

Answer 1

A

Step-by-step explanation:

Answer 2

A

Step-by-step explanation:

In living organisms, enzymes speed up the rate of chemical reaction by lowering the activation energy thereby bringing the reactants close to each other and weakened their chemical bonds which will enable the reactions to be faster.
