49. The functional model explaining Golgi transport by proposing that the cisternae themselves physically shift forward through the stack while modifying their contents is the

A. Vesicular transport model
B. Cisternal maturation model
✓
C. Static compartment framework
D. Fluid mosaic diffusion system

📝 Explanation

The cisternal maturation model states that cis-cisternae physically mature into medial and then trans-cisternae, receiving recycling enzymes from behind via COPI vesicles.
