A cell is hypertonic to its environment. Will the cell crenate or swell? Which has a
lower osmotic potential, the cytosol of the cell or the interstitial fluid?
Give this one a try later!
1. If a cell is hypertonic to its environment, the cell will swell up, and
potentially lyse.
2. The cytosol of the cell has a lower osmotic potential (i.e., more dissolved
solute)
What is the function of the Golgi apparatus?
Give this one a try later!
, The Gogi apparatus modifies, sorts, packages and distributes proteins it
receives from the RER
One human cell can synthesize a fully functional inulin molecule. With recombinant
DNA technology, why are two bacterial cells required to make a fully functional
human insulin molecule?
Give this one a try later!
Bacterial cells cannot perform posttranslational modification. Therefore,
they cannot form the disulfide bridges between the two chains of insulin
What are the two main types of microtubule-associated proteins (MAPs)?
Give this one a try later!
Dynein and kinesin
What is the only type of functional group found in monosaccharides? What two
functional groups interact to form a disaccharide? What is the specific name of the
covalent bond that is formed between two monosaccharides to form a disaccharide?
Give this one a try later!
, 1. Hydroxyl in the cyclic conformation. Hydroxyl and carbonyl in the chain
form
2. Hydroxyl groups on each monosaccharide interact to form a
disaccharide
3. Glyosidic bond
What are the lives of evidence that support the endosymbiotic theory?
Give this one a try later!
Mitochondria have a double membrane, their own circular DNA, their own
ribosomes and can divide on their own as well. They are also susceptible to
antibiotic therapy just like bacteria
What is the difference between simple diffusion and facilitated diffusion?
Give this one a try later!
In simple diffusion molecules cross the membrane on their own (i.e., the
plasma membrane itself is the pathway). In facilitated diffusion, molecules
require a transport protein to assist their movement across the bilayer (i.e.,
the transport protein is the pathway). In both circumstances, a
concentration gradient is required as the energy source
Organelles are not listed as one of the levels of organization of life. Can you put forth
a logical argument for why they are not part of the hierarchy of life?
Give this one a try later!
, Organelles are structures within cells. They develop within cells after cells
are made from molecules and therefore do not exist prior to the existence
of cells as stand-alone structures
What vitamin deficiency leads to scurvy? Is this vitamin water- or fat-soluble?
Give this one a try later!
1. Vitamin C
2. Water-soluble
Is phosphocreatine made while you are exercising?
Give this one a try later!
During rest
Can you explain a few ways in which a cell could become depolarized?
Hyperpolerized?
Give this one a try later!
Cells become depolarized when ions such as Na+ or Ca2+ flow into the cell
and make the cell less negative on the inside, and therefore less polarized
Cells become hyperpolarized when ions such as Cl- enter the cell of when
K+ leaves the cell
