33. Which of the following contribute to the asymmetric nature oflipids in the plasma membrane?
A) There is a limited set of enzymes that transfer specific lipidhead groups during lipid biosynthesis.
B) The enzymes that catalyze glycolipid synthesis are only found onthe lumen side of the ER
membrane.

1/What is the fate of a protein with no N-terminus Signal Sequence?

(a)Transport through the constitutive secretory pathway

(b)Dispersal throughout the cytoplasm

(c)Transport into the nucleus

2/ In nerve cells, Botulinum toxin-A degrades a subunit of a T-snare localized on the plasma membrane, how would this affect vesicular trafficking?
