The main component of the plasma membrane, the ______________________ molecule, has both
polar and non-polar areas. The non-polar
portions of this molecule form the hydrophobic barrier between the hydrophilic
fluid inside the cell, also known as __________________ and the hydrophilic
fluid outside the cell, also known as __________________________.
Microvilli increase _____________________ while
similar looking structures called cilia _______________________________.
Rough ER is rough because it contains
_________________ that produce these workhorses of the cell
The ‘post office’ of the cell is the
_________________, so-called because its job is to
______________________ is the process that
copies the message from DNA to mRNA and it occurs in this part of the cell
___________________. Translation, on the
other hand uses the mRNA copy to assemble __________________ in this part of
the cell ___________________.
Name 2 of the 6 types of proteins found on the
plasma membrane and state their function.
Is the DNA in the chromatin or chromosome
A cell in metaphase _____________________
A cell in interphase _____________________
DNA that can be accessed for transcription
State the location in the cell and be
specific. Some may be in multiple
Diffusion, osmosis, or transport? And what moves where?
Red blood cell in 10% NaCl
Na+ ions inside a cell _________________________________
Body perfume on your instructor
Glucose outside a cell
4 factors that influence the rate of diffusion. _______________________
is the transmembrane potential and what protein establishes one?

13. In anatomy and chemistry lab many students are exposed
to chemical preservatives, phenol, formaldehyde, alcohol. Our cells break down
these toxins very effectively. What cellular organelle is responsible for this?
14. A bacterial infection in intestine tract blocks many
membrane proteins in epithelial cells
and interferes with salt absorption but
not water exchange. Do you expect this person shows the sign of diarrhea or
15. Cystic fibrosis (CF) is caused by misfolded proteins
related to specific membrane chloride channel.
The result is accumulation of thick mucus that compromises several
organs including lung. The thick and sticky mucus clogs
the tubes that carry air in and out of your lungs. This can cause; A persistent
cough that produces: thick spit and mucus, Wheezing,
Breathlessness, A decreased
ability to exercise, Repeated lung infections, Inflamed nasal passages or a stuffy nose and death, You suspect which organelle in Cell is
responsible for this disease?
16. Michael was a pleasant, happy
infant who seemed to be developing normally until about six months of age. Able
to roll over and sit for a few seconds, suddenly he seemed to lose those
abilities. Soon, he no longer turned and smiled at his mother's voice, as he
had before, and he did not seem as interested in his mobile as he once was.
Concerned about Michael's reversals in development, his anxious parents took
him to the doctor. It took exams by several specialists to diagnose Michael's disease.
A neurologist clinched her suspicion of Tay-Sachs by looking into Michael's
eyes, where she saw the telltale cherry red spot indicating the illness. A look
at his cells provided further clues-- tiny enzyme-filled sacs, were swollen to
huge proportions while lacking one of the forty types of enzymes for degrading
materials, resulting in a disease that built up lipid material on his nerve
cells. His nervous system would continue to fail, and he would be paralyzed and
unable to see or hear by the time he died, before the age of four. Which cellular
organelle was swollen under microscope and lacked the enzyme?
17. Oncovin is a drug that damages mitotic
spindle. Why such a drug can be used as a chemotherapeutic drug used to treat
18. A sterile male patient with
respiratory problem have a genetic
disease which affects both cilia
and flagella . You suspect the affected gene is related to …………………………………………..in
