How are proteins normally transported into the mitochondrial matrix, if they were originally synthesized on ribosomes present in the cytosol (not on the rough endoplasmic reticulum)? they are packaged into vesicles with v-SNARES for fusion with their target organelles they can pass freely through large pores in the inner mitochondrial membrane they are secreted by the golgi, captured by receptors, and absorbed by endosomes they must pass through the nuclear envelope by means of nuclear pores they are unfolded in the translocation channel, then refolded by chaperones

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.
