Plz help me!

2.If the shape of the acid alpha-glucosidase (GAA) enzyme changes, how would that affect the enzyme’s job in the cell?

A.Enzymes are like a lock and key, so if you changed the shape of the lock (GAA enzyme), the key (the glycogen) would no longer fit and wouldn't be able to get broken down into glucose.

B. Enzymes are like a lock and key, so if the enzymes shape changes, it will then get used up by the GAA and won't be available to break down glycogen.

C.There are so many GAA enzymes that it won't matter if the shape of one changes. The other enzymes will be able to work properly and break down the glucose.

D. The enzyme's job is to break down the glycogen in the lysosomes of the cell.

Answer 1

Its A enzymes are like a lock and key, if it is changed it wont fit, and they enzyme cant break down the glucose.

Answer 2

The right answer is A.

We have found more than 200 important mutations of the GAA gene, which alter the proper functioning of acid alpha glucosidase, reducing its activity and generating an excess accumulation of glycogen in lysosomes. This accumulation leads to Pompe disease, or glycogen storage disease II.
