The principal pathway for transport of lysosomal hydrolases from the trans Golgi network (pH 6.6) to the late endosomes (pH 6) and for the recycling of M6P receptors back to the Golgi depends on the pH difference between these two compartments. From what you know about M6P receptor binding and recycling and the pathways for delivery of material to lysosomes, describe the consequences of changing the pH in those two compartments. A. What do you suppose would be the fate...

1. what are some of the properties which make water a good environment for chemical reactions ? 2. What is an acid? Base? What is considered acidic or basic or neutral? Which substance/ compound is neutral? Know the pH scale—what does it tell us, what is it based on (its relation to H+ ion concentration)? It ranges from 0 to 14. Know which points/numbers on the scale are acidic, which are basic, which is neutral. What is the difference in...

1. a. Many medications are absorbed into the blood through the cells lining the stomach and small intestine. The rate of absorption (passage through a cell membrane into the blood stream) for a molecule depends on the structure and properties of the molecule. Which substance would be more easily absorbed into the blood stream; a polar, ionic, or nonpolar substance? Choose one and justify your reasoning using chemical and molecular details. b. Furosemide is a diuretic used to treat fluid...
