True or False:Each Golgi cisternae matures by moving upwards through the Golgi.
A
True
B
False
Verified step by step guidance1
Understand the structure of the Golgi apparatus, which consists of a series of flattened membrane-bound sacs called cisternae.
Learn about the cisternal maturation model, which suggests that cisternae themselves mature as they move from the cis face to the trans face of the Golgi apparatus.
Recognize that in the cisternal maturation model, the cisternae do not move upwards; instead, they mature by acquiring and losing specific enzymes and proteins as they progress through the Golgi.
Differentiate between the cisternal maturation model and the vesicular transport model, where vesicles carry proteins between static cisternae.
Conclude that the statement 'Each Golgi cisternae matures by moving upwards through the Golgi' is false because the cisternae mature in place by changing their composition, not by physically moving upwards.
