Describe How Molecules Enter and Leave a Cell
A hypertonic solution has more solutes. Passive transport is the movement of molecules and ions across the cell membrane whith no use of energy it usuale involves a difussion down its concentration gradient a region where concentration changes across a membrane from higher to lower concentrations. Transport In And Out Of Cells In vesicular transport vesicles allow large molecules to exit the cell because the vesicle fuses with the plasma membrane and its contents spill out. . These channels only remain open for approximately one millisecond but more than 7000 sodium ions pass through into the cell in this time. Define tonicity and describe its relevance to passive transport. This is called exocytosis. Leave a Reply Cancel reply. Through passive transport molecules move from an area of high concentration of low concentration this process is diffusion. Flagella and cilia also help with the movement of cells. ...
