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.
The most proficient process of generating ATP for most organisms is the aerobic respiration. What molecule is needed for aerobic respiration?
If succinate is employed as the electron donor in oxidative phosphorylation, then how many ATPs must be generated for each pair of electrons donated by the succinate?
Compare and contrast the electron transport systems (ETS) used in the aerobic respiration and the light reactions of photosynthesis. Comprise a description of the inputs and outputs of each ETS and
Aliens land. You find out that in almost all ways, their metabolism is similar to that of humans. One significant difference is that they don't use NAD/NADH. At each and every step in the oxidation
Cell respiration has three portions: Glycolysis, the Krebs cycle, and the electron transport chain. Where in the cell is each found, the molecule(s) which enter each, the molecules at the end of eac
Explain how are carbohydrates significant in RNA and DNA? Explain how do they function as part of DNA and RNA? What's their significance in the construction of the body organs and nerve cells?
In what manners are carbohydrates, lipids, proteins and fibers similar in relation to health, morbidity and mortality? In what manners are they dissimilar?
Compute the isoelectric point (pI) of each of the given amino acids: a) Glycine b) Glutamic acid c) Arginine
Compute the iso-electric point of a protein. I understand that you want to substitute variations of pH until you find out a pI which is close to zero.
An mRNA can be translated by numerous ribosomes at the same time, making a complex called a polysome. How might this capacity be a benefit to the cell?
If a double-stranded DNA molecule was 32 percent cytosine, what would be the percentage of guanine, adenine and thymine? Name the types of RNA delivers amino acids to the site of protein synthesis?
At what substrate concentration will an enzyme characterized by the kcat of 30 s-1 and Km of 0.005 M show one quarter of its maximal rate?
The enzyme carbonic anhydrase is found in the erythrocytes, and consists of a molecular mass of around 30000 Da. The hydration reaction catalyzed by this enzyme is reversible, and plays a vital role
You have just completed a meal comprising of a steak, baked potato and a vegetable. What enzymes would be discharged to digest this meal? From where would each of these be discharged? Explain why is
Food preservation processes interfere with the enzyme action of microbes and prevent them from surviving. How do canning, freezing, pickling and salting interfere with the enzyme activity? Ideas are
