Compare and contrast biochemical pathways. Describe the chemistry of the last three steps of the TCA. Describe the chemistry of the first three steps of β-oxidation. Explain how these pathways are similar and how they differ in terms of their chemistry, the involvement of coenzymes and the fate of the electrons. Describe the two connections between the urea cycle and the citric acid cycle

Select the best answer. What pathways generate reduced cofactors (NADH or FADH2) for the Electron Transport Chain to use? 1. Glycolysis 2. Gluconeogenesis 3. Pyruvate Dehydrogenase Complex Reaction 4. Citric Acid Cycle 5. Fatty Acid β-Oxidation   Question 18 options:   1, 3, 4   2, 3, 4   1, 3, 4, 5   2, 3, 4, 5   1, 2, 3, 4, 5

a. Calculate how  many carbons from an original glucose molecule will enter into the TCA cycle? (please provide your answer in number like 1, 2, 3)   b. Based on the question you answered above what happens to the carbons that do not enter the cycle (write what it converts into)?

Give typed explanation of both otherwise leave it

Write out the citric acid cycle. Show specific structures for each step. DO NOT write anymechanisms but do show what leaves the cycle at each specific step. Include partial but revealingstructures for the coenzymes and co-substrates used in the cycle.

Draw TCA Cycle.  Please make sure to state all the enzymes and co-factors for each step of the pathway.

Puting a metabolic pathway map together which includes glycolysis, gluconeogenesis, glycogen synthesis & glycogenolysis, and the two types of fermentation, and pyruvate oxidation (to acetyl-CoA). The map should have/illustrate/show all of the indicated 6 pathways stated previously on the same page, to emphasize how these processes are related to each other.   map should include:   a) Clear labels for all the pathways   b) All the pathways shown on the same page and correctly integrated with each other, i.e., it should be clear which reactions are shared by different pathways   c) The names of all metabolites (common abbreviations may be used)   d) The names of all enzymes   e) All relevant cofactors/co-substrates discussed in class, clearly showing, where ATP is used and produced   f) Double or single arrows representing reversible or irreversible reactions, respectively   g) All "high-energy" intermediates clearly labeled with an asterisk (*)   h) Labels for cellular locations of…

Explain well. Asap
