When animal cells undergo apoptosis (programmed cell death), phosphatidylserine, which is normally confined to the cytosolic monolayer of the plasma membrane, rapidly translocates to the extracellular monolayer. The presence of phosphatidylserine on the cell surface serves as a signal that promotes removal of the dead cell. How might a cell promote this redistribution of phosphatidylserine during apoptosis

The graph below compares the rates of reaction of a burning candle and an exploding firework. comparing chemical reactions what can you conclude from the graph? the reaction that causes a firework to explode requires less energy to start, and occurs more rapidly than the reaction that causes a candle to burn. the reaction that causes a firework to explode requires less energy to start, and occurs less rapidly than the reaction that causes a candle to burn. the reaction that causes a firework to explode requires more energy to start, and occurs less rapidly than the reaction that causes a candle to burn. the reaction that causes a firework to explode requires more energy to start, and occurs more rapidly than the reaction that causes a candle to burn. mark this and return
