Explanation / Answer

24. ER signal sequence contains multiple lysine and arginine residues
- true. They are helpful in signalling.

25. The plasma membrane is a sorting station of inward endocytic pathway.
- true. It is selectively permeable in nature and sorts out the inward endocytic pathway of many molecules.

26. The trans Golgi functions as a sorting station of outward secretory pathway.
- true. It Golgi maintains balance and movement of molecules outside to the cell.

27. Vesicles budding from ER are coated with Clathrin
- true. Clathrin and adaptins aid in bud formation.

28. RabGTPases and tethering proteins are the major specificity determinant of vesicle transport system.
- true. These aid in vesicle transport system.

29. v-SNARE proteins are one of the tethering proteins

- false. It is an orgenelle specific protein.
