Question

how would the lack of a cofactor for an enzyme affect that enzymes function?
the enzyme would function more quickly.
the enzyme would cease to function after reaching a maximum rate.
the enzyme would function more slowly.
the enzyme would not be able to function.
the enzymes function would not be altered.

Explanation:

Cofactors are non - protein chemical compounds or metallic ions that are required for an enzyme's activity. Without a cofactor, the enzyme's active site may not be in the proper conformation to bind to the substrate, thus the enzyme would not be able to function.

Answer:

The enzyme would not be able to function.
