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

membrane
D) oxygen is not available to bind with sodium to maintain it outside of the cell
Ans: C- the osmotic pressure is increased, which pulls additional sodium across the
cell membrane
