An experiment was performed to determine the effects of an inhibitor on the breakdown of glycogen by an enzyme. In an accompanying experiment.
You have isolated a factor from the blood of a space alien and named it XFF (for X-files factor). Based on preliminary data, you think that XFF could be one of three compounds normally found in huma
What is the role of the urea cycle, and what are the effects on an individual of a deficiency in one of the required enzymes.
The same domains and/or motifs are found in many proteins. In fact, a protein's tertiary structure is more conserved (stays the same or similar over many generations) than its amino acid structure.
Describe in your own words how Christian Anfinsen's ribonuclease renaturation experiments showed that amino acid sequence determines tertiary structure.
Bisphenol A (BPA) binds to estrogen receptor with a Kd of 2.1 x 10-7 M and an association rate of 1.3 x 106 M-1s-1. Calculate the dissociation rate, kd, including appropriate units.
If you were offered a procedure that allowed you to acquire this ability, would you accept? Why or why not.
I would also like to know how DDT is transported through the cell membranes. Is it passive diffusion, facilitated diffusion, filtration, active transport, etc. I know it is lipid soluble.
A paragraph description is included that tells in relative detail the various steps, and then a brief numbered list of events is given for quick reference in order to improve understanding of this c
Since all action potentials are identical, the intensity of a sensation depends on.
I thought if a positively charged residue was the c-terminal end of the primary peptide, then I should have seen fragments from carboxypeptidase B, since there is no blocking proline by either the A
Draw the structure of butanol and show water molecules in hydrogen bonds to the butanol. How many should there be? remember the H bonding rules.
Name the three major components of a homeostatic control system and tell briefly the function of each component.
Based on the H bonding you showed above, do you expect dihydroxyacetone to be quite water soluble or not -- in either case, explain your answer.
plan the structure of ribose-5-phosphate (draw out ALL bonds including the bonds within the alcohol FG).
In a prolonged fast, plasma glucagon levels are elevated. Describe how this hormone leads to an activation of fatty acid oxidation and explain why this adaptation leads to a gradual but pronounced r
LDL particles have a higher percent content of cholesterol and cholesterol esters than VLDL particles. Describe the catabolism of the VLDL particles that occurs in the circulation and how this accou
answer the question, consider how each system would do some simple job normally done by the other system (it can be done). You can assume that any neurotransmitter could be a hormone (stored and rel
What energy transformations occur between glucose and ATP.
Summarize the process whereby energy is obtained by glucose oxidation. (Please note- you could make this a very long answer, but just focus on the shortened/abbreviated steps.)
State the key products of the Kreb's Cycle and how many of each there are starting from 1 glucose molecule.
Multiple sclerosis is an autoimmune disease where the myelin sheath surrounding CNS axons is progressively lost. How will this degradation affect the generation of action potentials.
How does a catalase test help differentiate between Staphylococcus from Streptococcus sp.
Some theorists argue that there may be no clear threshold for effects such as carcinogenesis & mutation. What arguments do you think they might put forward in support of this.
Find any media piece (article, video, presentation, song, or other) related to scientific method and describe how it helped to better understand how the scientific method is used to create hypothese
