Question 4 1 pts Which of the following statements is FALSE about the movement of materials through the Golgi complex? Enzymes within the Golgi complex may modify proteins as they pass through the organelle. The CGN may send proteins back to the ER The TGN is a sorting station where proteins are segregated into different types of vesicles headed either to the plasma membrane or to various intracellular destinations. Membranes of the Golgi complex contain proteins that are also found in the plasma membrane. Lysosomal proteins enter the Golgi complex at its trans face and then pass across the stack to the cis face.

Which one of the following statements is true about the Golgi apparatus? Glycosylation of certain secretory proteins occur prior to the protein's entry into its lumen. Its composite flattened cisternae are continuous with one another It is typically associated with small secretory vesicles located near its cis face It is oriented in the cytoplasm so that its cis face is closest to the endoplasmic reticulum Transit of a secretory protein occurs in a direction from its trans face to its cis face.

Which of the following is true regarding the Golgi apparatus? the Golgi apparatus is an organelle surrounded by a single "cisterna" membrane, and contains enzymes that degrade defective cellular proteins or proteins brought into the cell by endocytosis each cisterna of the Golgi apparatus contains different enzymes that modify proteins as they move from the cis Golgi to the trans Golgi synthesis of a protein begins in the first cisterna of the Golgi, and continues as the protein moves through the Golgi so that 10-15% of the protein sequence is added within each cisterna the Golgi apparatus is composed of several membrane-bound cisternae connected by tubules so that all of the enzymes that modify proteins moving through the Golgi share one common lumen space

The TGN, trans-Golgi network, is the site of multiple sorting processes as proteins and lipids exit the Golgi complex. Compare and contrast the sorting of proteins to lysosomes versus the packaging of proteins into regulated secretory granules such as those containing insulin. Compare and contrast the sorting of proteins to the basolateral versus apical cell surfaces in MDCK cells versus hepatocytes.
