a. lysosomes
b. ribosomesc. smooth
endoplasmi c reticulum
d. golgi complex: Lysosomes
3. Which component of the cell produces hydrogen peroxide (H2O2) by using oxygen to remove
hydrogen atoms from specific substrates in an oxidative reaction?
A) lysosomes
,B) peroxisomes
C) ribosomes
D) oxyhydrosomes Ans: B- peroxisomes
4. The difference between eukaryotes and prokaryotes is that
eukaryotes:
a. all of these answers are correct
b. are smaller in size
c. contain organelles
d. have no nuclear membrane: Contain organelles and complex internal membranes
5. Ans: B- influx of calcium ions halts adenosine triphosphate (ATP)
production-
: 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
C) edema from an influx in sodium causes a reduction in ATP production
D) potassium shifts out of the mitochondria, which destroys the infrastructure
6. Which of the following is function of Golgi?
a. Packages protein for secretion to the outside of the cell
b. Produces ATP for cell function
,c. Contains hydrolytic enzymes
d. Is the site of protein synthesis in a cell: Packages protein for secretion to the
outside of the cell
7. Ans: A- apoptosis involves programmed cell death of scattered
singe cells: -
Which statement is a description of one of the characteristics of apoptosis?
A) apoptosis involves programmed cell death of scattered single cells
B) apoptosis is characterized by the swelling of the nucleus and the cytoplasm
C) apoptosis involves unpredictable patterns of cell death
D) apoptosis results in benign malignancies
8. Ans: C- the osmotic pressure is increased, which pulls additional
sodium across the cell membrane: 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

c. Packages protein for secretion to the outside of the cell
d. Produces ATP for cell function: Is the site of protein synthesis in a cell
10. Ans: A- adipose cells contain little water because fat is water
repelling: Obesity creates a greater risk for dehydration in people because:
A) adipose cells contain little water because fat is water repelling
B) the metabolic rates of obese adults are slower than those of lean adults
C) the rates of urine output of obese adults are higher than thos of lean adults
D) the thirst receptors of the hypothalamus do not function effectively
11. What genetic process is likely responsible for the
occurrence of asthma in only one of a pair of identical twins?
a. genomic imprinting
b. epigenetic modifications
c. methylation
d. transgenerational inheritance: Epigenetic modifications
12. Transcription is best defined as a process by which
a. A base pair substitution results in a mutation of the amino acid
sequence
