Plz! 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.

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

it has to be understood that the sea water contains a huge amount of sodium and chlorine ions and if they enter the cell of the atlantic cod fish, the cell will shrivel and the fish will die. to avoid such a condition, the fish uses active transport for the purpose of removing the ions against the gradient.

explanation:

the atlantic cod is not a maritime osmoconformer. its native application of salts is less than that of the seawater it lives in. it is continually falling water from the gills to the ocean via osmosis.

countering that, the fish is going to be swallowing seawater. but since its internal collection of salts is lower than seawater, the fish will want to go free of excess salt, and since that's going upon a gradient, then active transport, requiring energy, must be used to pump out the salt. much marine fish use the organs to filter out the salt and these fish discharge very straight urine.
