Describe7 marksChallenge

A pancreatic acinar cell secretes large quantities of digestive enzymes. Describe how the structure and function of the rough endoplasmic reticulum (RER) and Golgi apparatus enable this cell to produce and release these proteins.

How this question is marked

7 marks, so the mark scheme is looking for about 7 separate creditworthy points. Making the same point twice in different words earns it once.

Describe means: Say what happens or what something is like, in order and with detail. You are not being asked why. If there is data, quote it: name the trend, then give figures with units at the points where it changes.
