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.
A number of major worldwide industries are based on anaerobic respiration in a lower form of organism. Can you help me identify a couple of these industries and explain how anaerobic respiration pla
You think that your unknown organism does not ferment mannitol. There are two tests that you can perform to determine if your unknown organism ferments mannitol. What are the two tests.
How are carbohydrates important in RNA and DNA? How do they function as part of DNA and RNA.
explain Carbohydrate molecules. explain Carbohydrate molecules.
Which of the following illustrates the correct sequence of events in the synthesis of a protein molecule.
You start with a normal functioning cell where all parts of protein production are working properly. You treat a cell with RNAase that prevents production of mRNA. For each of the following molecule
calculate the isoelectric point of a protein. I understand that you need to substitute variations of pH until you find a pI that is close to zero.
You have isolated a new protein and are in the process of characterizing it. Several pieces of data about the protein are presented below. What can you deduce about the structure of this protein at
Packing together of two or more adjacent folded sections within a contiguous piece of polypeptidechain (found to occur in many unrelated proteins)
Assume that protein synthesis always reads along a chromosome. How are these two types of mutations likely to affect the protein coded for by a mutant gene.
