4. Oxaloacetate uniformly labeled with 14C (ie with equal amounts of 14C in each of its carbon atoms) is condensed with unlabeled acetyl-CoA. After a single pass through the citric acid cycle back to oxaloacetate, what fraction of the original radioactivity will be found in the oxaloacetate?

You are carrying out an experiment in the lab to study the citric acid cycle. To do this, you add 14C-labeled pyruvate at carbon 3 (this is the methyl carbon) to metabolically active mitochondria. Based on your knowledge of the citric acid cycle, what is the location of the 14C-label in oxaloacetate after one turn of the cycle? How many turns of the cycle are required to release all of the14C-label as CO2? Be sure to justify your answers by...
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...

10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
