Question 1 (5 points)

hydrogen atoms from specific substrates in an oxidative reaction?
Question 1 options:
Lysosomes
Peroxisomes
Ribosomes
Oxyhydrosom
es Question 2 (5
points)
What is a consequence of plasma membrane damage to the
mitochondria? Question 2 options:
Enzymatic digestion halts deoxyribonucleic acid (DNA) synthesis.
Influx of calcium ions halts adenosine triphosphate (ATP) production.
Edema from an influx in sodium causes a reduction in ATP production.
Potassium shifts out of the mitochondria, which destroys the
infrastructure.
Question 3 (5 points)
Which statement is a description of one of the characteristics of
apoptosis? Question 3 options:
Apoptosis involves programmed cell death of scattered single cells.
Apoptosis is characterized by the swelling of the nucleus and
the cytoplasm.
Apoptosis involves unpredictable patterns of cell death.
, Apoptosis results in benign malignancies.
Question 4 (5 points)
During cell injury caused by hypoxia, sodium and water move into the
cell because: Question 4 options:
During cell injury caused by hypoxia, sodium and water move into the cell because:
The pump that transports sodium out of the cell cannot function because of a decrease in
adenosine triphosphate (ATP) levels.
The osmotic pressure is increased, which pulls additional sodium across the cell membrane
Oxygen is not available to bind with sodium to maintain it outside of the cell.
Question 5 (5 points)
What is an effect of ionizing radiation
exposure? Question 5 options:
Respiratory distress
Sun intolerance
Deoxyribonucleic acid
(DNA) aberrations
Death
Question 6 (5
points)
Obesity creates a greater risk for dehydration in people
because: Question 6 options: chapter 3 q.2
?Adipose cells contain little water because fat is water repelling.
The metabolic rates of obese adults are slower than those of lean adults.
The rates of urine output of obese adults are higher than
those of lean adults.
The thirst receptors of the hypothalamus do not function effectively.
