Over 200 word essay in regards to the sources of antioxidants and how free radicals influence the human body. In addition, the optimal delivery of vitamin C with the human body.
1) Write down some similarities and differences between the macro and micronutrients? 2) Explain why it is significant to understand what macro and micronutrients are and how they work in the body?
Can anyone explain to me the relationship of T-cell receptors, MHC (class I and II), their antigen presenting cells and their roles in the adaptive immune response?
Describe the selective benefit of keeping the surface to volume ratio high in a cell? a) It gives more volume to store more nutrients. b) This maximizes the relative surface area for cooling.
Electrolyte balance is much significant in our body. This balance can even greatly affect our heart functions - causing arrhythmia or even a heart attack.
If p-nitro phenyl phosphate had been employed as a substrate, would the same Km have been obtained? Describe.
Exhibit how a peptide bond forms between the two amino acids, glycine and valine. Draw the structural formulas for the reactants and the product. Label the functional groups and linkages present.
Explain how would you expect a nonhydrolyzable GTP analogue to influence signaling events which take place during the stimulation of a liver cell by glucagon?
Compare and contrast the signaling by neurons which secret neurotransmitters at synapses to signaling carried out by endocrine cells, which secretes hormones to the blood, describe the relative ben
If cell surface receptors can quickly signal to the nucleus by activating latent gene regulatory proteins like STAT's at the plasma membrane, explain why do most cell surface receptors use long, ind
The external faces of some of the proteins in the plasma membrane encompass carbohydrate groups attached to them. What role do such "sugar-coated" proteins play in the life of the cell?
The solution details how such signaling defects associate to the immunosuppression see in these conditions, and the differences between such diseases.
A B-cell has internalized a toxin which comprises the epitope recognized by its surface Ig. Explain how this cell would be activated, the cellular and molecular interaction(s), and the different ste
Paracrine signaling molecules should be prevented from straying too far from their points of origin in order to remain localized. Explain how can this be accomplished?
Where 273 = standard temperature in K. and 760 is standard pressure in mmHg (Torr), compute the rate of O2 consumption for normal and freeze-thawed lentils (consumption rate = slope of the line) at r
C14-Glucose labeled at carbon 5 enters glycolysis, is made to pyruvate, then acetyl CoA, and enters the TCA cycle. Explain how much of the C14 will be discharged as CO2 throughout the second turn of
In brief describe the process of cellular respiration and uses of the energy obtained from the process. Your answer must comprise the given terms: glucose, water, carbon dioxide, chemical energy and
Compare and contrast the efficiency of producing ATP via aerobic respiration, anaerobic respiration, and fermentation.
Explain the method by which food energy is transformed to the chemical energy of ATP in living cells. Go through each of the main steps in the process, comprising the starting and ending product of
After falling to an abandoned well, a young boy is rescued after he nearly drowns. He is found to have high levels of CO2 and lactic acid and low levels of O2. Diagnose the boy's condition and propose
A number of main worldwide industries are based on the anaerobic respiration in a lower form of organism. Can you help me to recognize a couple of these industries and describe how anaerobic respira
You suppose that your unknown organism doesn't ferment mannitol. There are two tests which you can perform to find out if your unknown organism ferments mannitol. Describe the two tests?
Please explain the differences between the two respiratory pathways (aerobic and anaerobic.) I would as well like to know more regarding the net ATP produced from each.
Flask A has yeast cells in glucose-minimal salts broth incubated at 30C with aeration. Flask B has yeast cells in a glucose-minimal salt broth incubated at 30C in an anaerobic jar.
The role of oxygen molecules needed for aerobic respiration is: a) To accept the low energy electrons at the end of electron transport chain. b) To form ATP. c) To produce CO2.
