Question

Which organelle has a key role in the transformation and turn over of membranes within the cell?

Answer 1

Golgi apparatus has a key role in the transformation and turnover of membranes within the cell. Golgi apparatus is a complex cytoplasmic structure made up of smooth membrane saccules or cisternae, a network of tubules with vesicles and vacuoles, which takes part in membrane transformation, secretion, and production of complex biochemicals. Golgi complex brings about membrane transformation, that is, converting one type of membrane (e.g., that of ER) into other types (e.g., selectively permeable plasma membrane, differentiated membrane of lysosome). The complex also takes part in the recycling of plasma membrane.
