Lesson 4 Flashcards
iClicker: Collagen is an important protein in the human extracellular matrix. Therefore, it has to be secreted outside of the cell. Where would this protein be synthesized?
a. Rough ER
b. Smooth ER
c. Golgi body
d. Nucleus
e. Cytosol
A
iClicker: Collagen is an important protein in the human extracellular matrix. Normally, it is secreted outside of the cell. It also has to pass through the Golgi. Imagine the wrong carbohydrates/sugars were added in the Golgi. Which of the following is NOT a possible location you might find the protein?
a. Rough ER
b. Endosome
c. Golgi body
d. Extracellular matrix
e. Transport vesicle
D
iClicker: A particular individual has enlarged cells. Closer examination reveals an excess of dead, damaged mitochondria. Which organelle is most likely not functioning correctly?
a. Nucleus
b. Lysosome
c. Ribosome
d. Chloroplast
B
iClicker: Input of water into the plant vacuole causes it to swell and increase in size. Why does the cell not increase in size with the vacuole?
a. Plant cells do not have plasma membranes
b. The presence of the plant cell wall
c. The nucleus pushes the vacuole back
d. Water is a liquid and thus does not affect cell volume
B
iClicker: Which of the following would allow you to differentiate between plant and animal cells?
a. Presence of a nucleus
b. Presence of a mitochondrion
c. Presence of a Chloroplast
d. Both B and C
e. None of the above
C
iClicker: A mix of cells was identified in a pond sample. Following are the descriptions of the cell, which one is the bacterial cell?
a. ~50um; several green, membrane-bound organelles; large vacuole
b. ~1um; DNA free within the cell; thick cell wall
c. ~100um; amorphous; rough ER apparent; vesicles apparent
d. ~10um; single flagellum; distinct nucleus
B
iClicker: Eukaryotic cells are a factor of 10 larger than prokaryotic cells. What accounts for the difference in size?
a. Eukaryotes are only found in multicellular organisms, which means they have to be bigger
b. They have more nuclei so have to be larger to accommodate them
c. Organelles increase functionality which allows cells to be bigger
d. Prokaryotes divide by splitting so always get smaller
