CORRECT ANSWER What is a consequence of plasma membrane damage to the
mitochondria?
A) enzymatic digestion halts deoxyribonucleic acid (DNA) synthese
B) influx of calcium ions halts adenosine triphosphate (ATP) production

secretion to the outside of the cell
Ans: A- apoptosis involves programmed cell death of scattered singel cells -
CORRECT ANSWER Which statement is a description of one of the characteristics
of apoptosis?
A) apoptosis involves programmed cell death of scattered singel cells
B) apoptosis is characterized by the swelling of the nucleus and the cytoplasm

Ans: C- the osmotic pressure is increased, which pulls additional sodium across
the cell membrane - CORRECT ANSWER 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

d. Produces ATP for cell function - CORRECT ANSWER Is the site of protein
synthesis in a cell
