Answer 1

Ans.

Q6. - Chaperons are a group of proteins involved in cell homeostatsis. It has been established that chaperons play a key role in protein folding. They may also play a role in protein degradation.

Q7. - A protein without a signal sequence will be localized to the cytoplasm.

Q8. - Golgi to ER is an example of vesicles transport in retrograde direction.

Q9. - Importin receptor is not rquired for trnsportation of most proteins into ER.

Q10. - After binding to GTP SAR1 bind to the cytoplasmic leaflet of the plasma membrane.
