How does cell volume affect nutrient
WebThree terms—hypertonic, hypotonic, and isotonic—are used to describe whether a solution will cause water to move into or out of a cell: If a cell is placed in a hypertonic solution, there will be a net flow of water out of the cell, and the cell will lose volume. A solution will be hypertonic to a cell if its solute concentration is higher ... WebDeprivation of nutrients and other growth signals, as might be the case in the nutrient (and oxygen)-starved regions of a growing tumor, may encourage normal cells to exit the cell cycle into a resting or G 0 state. Therefore, mutations in signaling pathways that promote growth independently of growth factors and nutrient availability may ...
