Question 35 A cell just completed vesicular transport resulting in exocytosis of a protein. The protein Can now be found in the extracellular fluid (ECF) Can now be found in the intracellular fluid (ICF) Is likely going to participate in passive transport. Has now been moved from the Golgi apparatus to the Endoplasmic Reticulum. Is likely going to participate in active transport. 2 pts

The following organelles and structures are involved when a cell produces a peptide hormone for secretion. First the information that is stored in the __________ need to be transcribed and transferred in the form of mRNA to the __________ for translation into amino acid sequence. Then the polypeptide needs to by transported into the __________ for final processing, packaging and shipping in a vesicle that will travel on the intracellular transport made of the cytoskeleton elements to the __________ for exocytosis. The energy for this is process is provided in the form of ATP that is produced by the __________. Mitochondria; ribosomes; smooth ER; cell wall; lysosomes nucleus; rough ER; Golgi apparatus; cell membrane; mitochondria nucleolus; rough ER; Golgi apparatus; cell membrane; lysosome rough ER; Golgi apparatus; smooth ER; cell membrane; mitochondria nucleolus; rough ER; Golgi apparatus; cell wall; mitochondria

Proteins are synthesized and move through the endoplasmic reticulum; they are transported in vesicles to the Golgi apparatus where they are modified, and then they are transported in vesicles to the cell surface. They are then exported from the cell in a process called exocytosis. The reverse of this process, bringing particles from outside to the inside of the cell, is called endocytosis.

Vesicular transport from the Golgi apparatus may occur via 3 different pathways. Imagine yourself as a scientist specializing in membrane proteins. If your protein of interest needs to be present at the plasma membrane, which of the following pathways must this protein follow in order to be delivered to its correct destination? Pathway 1: This protein must be packaged as a component of the vesicles' membrane that will later fuse with the plasma membrane. Pathway 2: None of the listed pathways. Pathway 3: This protein must be packaged in the lumen content of secretory vesicles whose membrane will fuse with the plasma membrane to be secreted outside of the cell. Pathway 4: This protein must be packaged in the lumen content of vesicles that will later fuse with lysosomes.
