Gaucher disease, caused by the inhibited digestion of lipids, results in the accumulation of fatty acids within many organs in the body and leads to their subsequent dysfunction. Which of the following describes the most likely subcellular component and related process responsible for the development of Gaucher disease? A B C D Lysosomes contain insufficient amounts of enzymes necessary for the metabolism of lipids. The Golgi complex produces vesicles with highly permeable membranes that cannot ef- fectively regulate the movement of particles. Mitochondria are not producing a sufficient amount of ATP required for the digestion of lipids. The rough endoplasmic reticulum contains an unusually high number of ribosomes, re- sulting in an overproduction of digestive enzymes.

Osmosis

In simple words, osmosis is the slow, gradual movement of a liquid through a membrane. But there are nuances to this process. For instance, there has to be an imbalance in the distribution of solute in the liquid on either side of the membrane, which has to be semipermeable. The liquid in the region with a lower solute concentration moves to the region with a higher concentration, thereby displacing the solution in the process. The objective is to equalize the concentration of molecules on both sides of the membrane; the displacement of liquid can be viewed as a byproduct of this equalization. Since there is no energy required to carry osmosis, it is considered a passive process.
