Many eukaryotic organelles are involved in the production and shipping of proteins out of the cell.  Explain the pathway that a protein takes from its initial instructions through to its exportation from the cell. Include ALL organelles involved and explain their function.

Explain (using the correct terminology and drawing an image) what happens to the cells in the following environments: A human blood cell (0.9% salt) is placed in a saltwater tank (27.5% salt). - A bacterial cell with 35% organic material in their cytoplasm is living in a tank filled with 35% sulfur. - A freshwater plant cell (75% water) is living in a pond that floods over.

Vesicles forming at the plasma membrane, or at the trans face of the Golgi, and destined only to fuse with endosomes and lysosomes, are generally not associated with which of the following proteins? dynamin proteins cargo receptor proteins clathrin proteins collagen proteins adaptin proteins
