During cell injury caused by hypoxia, sodium and water move into the cell because:
,A) during cell injury cause by hypoxia, sodium and water move into the cell because:
B) the pump that transports sodium out of the cell cannot function because of a decrease in adenosine
triphosphate (ATP) levels
C) the osmotic pressure is increased, which pulls additional sodium across the cell membrane
