Protein synthesis — practice question

Protein production is controlled by a complicated chain of events and several cell structures.
(a(i))[2]

In Table 1.1, record the order in which the events happen, using $1$ for the earliest process in the sequence.

(a(ii))[3]

Using the list A to F below, select one cell location for each event and write the letter in Table 1.1. A letter may be used once, more than once, or not at all.

(b)[3]

Describe exocytosis.

(c(i))[1]
