Part 2: Glycolysis and Radiolabeling A common practice in biochemistry is the feeder study, in which radiolabeled substrate is fed to an organism; afterwards, radiolabeled metabolites are isolated and used to determine how the substrate was used by the organism. 4. Plants use intermediates from the glycolytic pathway as substrates for other pathways. For example, if we feed plants radiolabeled glucose, the radiolabel eventually ends up in the amino acid valine. If we feed the plants 6-(C)glucose i.e....

In a "pulse chase" experiment under anaerobic conditions, 14C glucose is added to an ethanol-producing yeast cell extract just long enough that each intermediate in the ethanol fermentation is labeled with a 14C (pulse). The 14C label is then diluted so that no additional radioactivity is incorporated into the intermediates (chase). 1. What position in ethanol will be labeled with 14C if 14C-glucose labeled at position C-1 is used? 2. Where should the 14C label sit in glucose for it...

The complex metabolic pathways in the parasite Trypanosoma brucei were elucidated in part by adding radiolabeled metabolites to cultured parasites. In the parasite, glucose is converted t0 phosphoenolpyruvate (PEP) in the cytosol. PEP then enters an organelle called the glycosome and is converted to oxaloacetate (OAA); OAA is then converted to malate, and malate to fumarate. Fumarate reductase catalyzes the conversion of fumarate to succinate; the succinate is then secreted from the glycosome. If C1 of glucose is labeled, what...

Question: You buy a sample of glucose that has the radioactive carbon-14 (C) isotope at the second position (Carbon #2). All other carbon positions in the glucose molecules have the "C isotope. "C is only a label and does not alter the biochemical behavior of the molecules in which it is found. This glucose sample is mixed with all the enzymes derived from liver cells, which initially contain no other C-labeled chemicals. A) Draw the Haworth structure of glucose and...

General Biology BIO121 Yeast Fermentation Lab Introduction Organisms stay alive by the utilization of energy through metabolism. The energy acquiring pathways in photosynthesis convert radiant energy from the sun into the chemical bond energy of carbohydrates. This photosynthetic process is limited to the producers or autotrophs, which include plants, photosynthetic bacteria and some protists....

Can you please explain in simple terms the methods of this experiment? I'm having difficulty visualizing and understanding what is being done. I have copied and pasted some of the text from the article. Thank you! Abstract : Obesity, high-fat diets, and subsequent type 2 diabetes (T2DM) are associated with cognitive impairment. Moreover, T2DM increases the risk of Alzheimer's disease (AD) and leads to abnormal elevation of brain beta-amyloid levels, one of the hallmarks of AD. The psychoactive alkaloid caffeine...
