Final answer:
If the endoplasmic reticulum of a cell became dysfunctional, the ability of the cell to produce proteins would be compromised.
Step-by-step explanation:
If the endoplasmic reticulum of a cell became dysfunctional, the ability of the cell to produce proteins would be compromised. The endoplasmic reticulum is responsible for protein synthesis in the cell. Without functional endoplasmic reticulum, the cell would not be able to produce the necessary proteins for various cellular processes and functions.
