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