Final answer:
A defect in Enz1 results in a deficiency of that specific enzyme, impacting the associated metabolic pathway. A defect in Enz4 also leads to a deficiency or dysfunction of that enzyme, affecting its associated metabolic pathway.
Step-by-step explanation:
In the given question, if there is a defect in Enz1, it results in a deficiency of the function or production of that specific enzyme. This means that the metabolic pathway or reaction associated with Enz1 might not occur properly, leading to various consequences depending on the specific pathway involved.
On the other hand, if there is a defect in Enz4, it results in a deficiency or dysfunction of that specific enzyme as well. Again, this can have various consequences depending on the metabolic pathway or reaction in which Enz4 is involved.
