3. If there is a mutation in the DNA that prevents the GAA enzyme from doing its job, what will happen to the structure and function of the lysosome?

A. The lysosome will swell and expand in size (structure) and it will not be able to break down the glycogen that is going to build up in the lysosome (function).

B. The lysosome will remain a small sac (structure) and the acid inside it will break down the glycogen (function).

C. The lysosome will shrink (structure) because it is sitting in a hypertonic solution, so the acid will diffuse out of the lysosome (function).

D. The lysosome will burst and acid will get all over the cell.

Answer 1

The lysosome will swell and expand in size (structure) and it will not be able to break down the glycogen that is going to build up in the lysosome (function).

Step-by-step explanation:

Answer 2

The correct answer is: A. The lysosome will swell and expand in size (structure) and it will not be able to break down the glycogen that is going to build up in the lysosome (function).

GAA gene codes for the acid alpha-glucosidase enzyme which is responsible for the break down of glycogen in the lysosome. Mutations in the gene cause glycogen storage disease type II (Pompe disease) characterized by accumulation of glycogen in the lysosome. Excessive glycogen storage can lead to interruption of normal functions of other organelles
