Which of the following statements regarding secretory vesicles is FALSE? Choose all that apply. The lumen of secretory vesicles is generally less acidic than the lumen of the TGN from which they originate. Proteins destined for secretory vesicles (for regulated secretion) often aggregate in the lumen of the TGN. Regulated secretion is considered to be the 'default pathway' through the endomembrane system Constitutive secretion is considered to be the 'default pathway' through the endomembrane system Proteins destined for the lysosome are packages into the same vesicles as other secretory vesicles.

Which of the following statements regarding secretory vesicles is FALSE? Choose all that apply. - Constitutive secretion is considered to be the 'default pathway' through the endomembrane system - Regulated secretion is considered to be the 'default pathway' through the endomembrane system - Proteins destined for secretory vesicles (for regulated secretion) often aggregate in the lumen of the TGN. - The lumen of secretory vesicles is generally less acidic than the lumen of the TGN from which they originate. - Sometimes secretory vesicles are actually larger tubules - Proteins destined for the lysosome are packaged into the same vesicles as other secretory vesicles.

(Q017) What is one of the main differences in the behavior of the proteins in a vesicle destined for constitutive secretion, and the proteins in the vesicle destined for regulated secretion? a. Proteins in the regulated secretion vesicle tend to aggregate and become highly concentrated in the ionic conditions in the vesicle. b. The regulated secretion vesicle proteins are bound to lipids for supplying the plasma with new lipids. c. Proteins in the constitutive secretion vesicle are stored for release in response to a signal. d. Proteins in the constitutive secretion vesicle unfold to keep the concentration in the vesicle low, and then refold at the cell surface.

Which of the following statements about secretion is FALSE? a. The membrane of a secretory vesicle will fuse with the plasma membrane when it discharges its contents to the cell's exterior. b. Vesicles for regulated exocytosis bud from the trans Golgi network and accumulate at the plasma membrane until the appropriate signal has been received. c. The signal sequences of proteins destined for constitutive exocytosis ensure their packaging into the correct vesicles. d. All of the above are True
