- ER lumen: C- terminus or N- terminus Golgi apparatus- C- terminius or N- terminus transport vesicles lumen- C-terminus or N-terminusIf a cell's lysosomes burst, the cell would ______. digest itself divide into two cells shrivel need to manufacture more lysosomesSecretory vesicles fuse with the cell membrane to release their contents to the outside of the cell. In this process, the membrane of the secretory vesicle becomes part of the cell membrane because small pieces of the membrane are continually added to the cell membrane, one would expect the cell membrane to become larger and larger as secretion continues. The cell membrane stays the same size, however. Explain how this happens.
- Secretory vesicles (destined for exocytosis) that fuse with the plasma membrane only in an intermittent manner (often requiring an environmental signal) are properly referred to as: constitutive secretory vesicles (like those that carry lipids, such as phosphatidylcholine) the v-SNARES the endosomes the t-SNARES regulated secretory vesicles (like those that carry hormones, such as insulin)Which of the following is reponsible for the synthesis of proteinsthat are being exported from the cell?a. smooth ERb. rough ERc. lysosomed. peroxisomeVacuoles are fluid-filled organellespresent in some cells.Which function isNOT normally performed by vacuoles?

- A melanosome (type of vesicle containing the pigment melanin) is transported towards the nucleus of the cell. The hydrolysis of ATP is involved with this movement. Identify the most likely motor protein and cytoskeletal filament involved with this transport.Secretory vesicles (destined for exocytosis) that fuse with the plasma membrane continuously, with no requirement for hormones or any other environmental signal, are properly referred to as: the v-SNARES constitutive secretory vesicles (like those that carry lipids, such as phosphatidylcholine) the endosomes regulated secretory vesicles (like those that carry hormones, such as insulin) the t-SNARESWhich statement is not true of endoplasmic reticulum? There is smooth and rough endoplasmic reticulum It is found in all living cells. Rough ER has ribosomoes bound to it.
