Quiz 3 for BSC 1005
Proteins can be labeled with radioactivity in order to trace their pathway through a living cell. Choose
the one list from below that represents the correct pathway of an antibody protein produced by an
immune system B cell. The pathway would start where they are made inside the cell to the point where
they exit the cell to enter the lymphatic or circulatory system. - ribosomes > rough ER > vesicles >
Golgi apparatus > vesicles > cell membrane (Protein production always starts with a ribosome. Then the
rough ER will "finish" and fold and package them, and send them via vesicles to the Golgi apparatus.
There they are further modified so they can be shipped, via vesicles again, to destinations either inside
the cell they were made, or outside of the cell membrane to foreign destinations, as in this case with the
antibodies.)
What is assumed to be the advantage of the long, folded inner membrane of the mitochondria? What do
the folds of the inner membrane do to make the mitochondrion more efficient? - increased
surface area for cell respiration reactions. (It is thought that the folded inner membrane increases the
surface area, which is the surface area of the mitochondria on which ATP is actually created via the
Electron Transport Chain.)
Viruses are members of which one of the three Domains of living organisms? - - Archea
- Bacteria
- Eukarya
- None
Answer: NoNE: Viruses are not considered to be living organisms, and therefore are not classified with
other living organisms into any of the three Domains that we put all other living things.
The cellular cytoskeleton of eukaryotes contains which of these types of protein fibers? - If it isn't
microtubules, intermediate filaments, and microfilaments (actin filaments), then it's wrong. Those 3 are
the three types of protein fibers.
Which structures within a cell are responsible for making (or more accurately, recharging) the ATP
molecules used for cellular energy? - mitochondria ; The mitochondria are the cellular power
plants.
