1. Which component of the cell produces hydrogen peroxide (H2O2) by using
oxygen to remove hydrogen atoms from specific substrates in an oxidative
reaction?
Lysosomes
Peroxisomes
Ribosomes
Oxyhydrosomes: peroxomes
2. What is a consequence of plasma membrane damage to the mitochondria?
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.: -
Influx of calcium ions halts adenosine triphosphate (ATP) production.
,3. 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.: Apoptosis involves programmed cell death of scattered
single cells.
, 4. 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.: The
pump that transports sodium out of the cell cannot function because of a decrease in adenosine triphosphate (ATP)
levels.
5. What is an effect of ionizing radiation exposure?
Question 5 options:
Respiratory distress
Sun intolerance
Deoxyribonucleic acid (DNA) aberrations
Death: Deoxyribonucleic acid (DNA) aberrations
6. 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.
