Plz 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.

The pharynx is the structure in the body that serves as a pathway of both air and food. how does the body make sure that food does not get into the lungs? the salivary glands secrete enzymes that pull food out of the air pathway. the small intestine pushes the air out of the digestive system. the pancreas breaks down food in the air pathway. the epiglottis closes the air pathway so that food will not enter it.
