- Cytochalasin D inhibits the formation of microfilaments. Which of the following biological activities will be affected? Select all that apply. Formation of nuclear lamin network Formation of cleavage furrow in telophase U Cytosolic transport of secretory vesicles Movement of phagocytic cellsSecretory 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.A cellular process is shown in stages from left to right in the image.
