How is a Scathard plot generated, and what measure of the inter-molecular interaction is used to determine this.
Two post-translational modification of proteins and indicate where the modification takes place within the cell and what effect it has on the protein.
Because G binds to C more strongly than A binds to T, the melting temperature should increase with the fraction of G/C pairs along the backbone of a sequence.
A new drug was found to decrease Hepatitis B virus. The drug is an analogue of one of the nucleic acid bases of DNA and probably works by being incorporated into the virus and disrupting viral genes
How would you expect the metabolism in the heart to change.
Glucose is frequently administered intravenonusly to patients as a food source. A new resident at the hospital suggests administering glucose-6-phosphate instead.
How many can the predictions above be used to determine the mechanism by which the fatty acids are released from the fatty acid synthetase.
If the acetyl CoA is labeled at the methyl carbon with tritium, and malonyl CoA is unlabeled, how many tritium atoms will be incorporated into each molecule of palmitate formed.
What functions are controlled by cortisol.
Why do they have that name, and how do they arise in metabolism? Explain why they accumulate under conditions of carbohydrate starvation or in diabetes.
How would you expect a nonhydrolyzable GTP analogue to affect signaling events that take place during the stimulation of a liver cell by glucagon.
Compare and contrast signaling by neurons which secret neurotransmitters at synapses to signaling carried out by endocrine cells, which secretes hormones into the blood, Discuss the relative advanta
What role do such "sugar-coated" proteins play in the life of the cell.
Cell respiration has three parts: glycolysis, the Krebs cycle, and the electron transport chain. Where in the cell is each found, the molecule(s) that enter each, the molecules at the end of each, a
Which 2 amino acids donate amino groups to other compounds for nitrogen metabolism? What citric acid cycle intermediate can be converted to aspartic acid upon acceptance of an amino group.
Calculate the number of protons in a respiring liver mitochondrian, assuming its inner matrix compartment is a sphere of diameter of 1.5 micro meter.
If succinate is used as the electron donor in oxidative phosphorylation, how many ATPs should be generated for each pair of electrons donated by succinate.
Compare and contrast the electron transport systems (ETS) utilized in aerobic respiration and the light reactions of photosynthesis. Include a discussion of the inputs and outputs of each ETS and al
for one electron pair, the amount of potential energy in the proton gradient which is theoretically available for ATP synthesis under standard conditions.
Aliens land. You find that in almost all ways, their metabolism is identical to that of humans. One important difference is that they do not use NAD/NADH.
In the presence of oxygen, some of this energy is ultimately converted into ATP production. However, no such conversion happens under anaerobic conditions. Explain why.
Instead of using yeast cells the same experiment was performed with Clostridium, an obligate anaerobe. Again flask A had aeration and Flask B was in an anaerobic jar.
The role of oxygen molecules required for aerobic respiration.
What molecule is required for aerobic respiration? Some microbes thrive in an anaerobic environment. How do they efficiently generate ATP in these conditions.
Why does the boy have high levels of CO2 and lactic acid and low levels of O2.
