Sar1A is a GTPase involved in a common process associated with these cellular structures. Along with actin regulation, ADP ribosylation factor controls breakdown and synthesis of these structures, while COP1 is involved in a retrograde method of moving these. Movement along microfilaments and microtubules by these structures is controlled by Rab proteins, which also inspect the binding of a type of protein classified as Qa, Qb, Qc, and R. Those SNAREs are responsible for the binding of these structures to membranes, after which they can release their contents via exocytosis. Clathrin coats these structures that transport materials between the Golgi body, endosomes, and the cell membrane and which often contain hormones, waste, or water. For 10 points, name these intracellular structures surrounded by a phospholipid membrane.
