) Describe the 10 enzymatic reactions of glycolysis and the  organization of the pathway in 2 main phases.

Identify all of the inputs and outputs for glycolysis, krebs cycle, and oxidative phosphorylation. What are the regulatory steps of these pathways and what do the key regulatory enzymes control? What compounds inhibit/activate these enzymes?

The diabetic body's reliance on ketogenesis to provide energy due to the unavailability of glucose causes serious health and toxicity concerns in these individuals. 1) Describe the role of ketogenesis in diabetes, why the body elects this metabolic pathway, and its resultant benefits and consequences. 2) Describe the role of ketogenesis in a ketogenic diet, why this can be considered a desired metabolic state for individuals, and the benefits and consequences of ketogenesis in these intentional circumstances.  Rationalize the differences between these two ketogenic instances.

For each step of the citric acid cycle, name the enzyme responsible for the chemical transformation that occurs and classify the enzyme type: Step 1. Step 2. Step 3. Step 4. Step 5. Step 6. Step 7. Step 8. i. oxidoreductase (oxidases, reductases, dehydrogenases) ii. transferase (transaminases, kinses) iii. hydrolase (lipases, proteases, nucleases, carbohydrases, phosphateses) iv. lyase (dehydratase, decarboxylase, deaminase, hydratase) v. isomerase (racemases, mutases) vi. ligase (synthetases, carboxylaces) Enzyme Name Enzyme Type

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)?

Consider a 24:1 △­­cis-9 fatty acid in the mitochondrion. For each fatty acid given, determine the following. 1. Gross ATP from b-oxidation cycles 2. Gross ATP from acetyl CoA produced 3. Gross ATP from conversion of propionyl CoA (if applicable) 4. Total number of ATP deducted 5. Total net ATP

Propose a pathway for the following compound to enter gluconeogenesis / glycolysis. In your pathway, include enzymes (you can use E1, E2, etc.) as well as any necessary cofactors.

1, For EACH of the following enzyme categories, (1) describe what the general function of the enzyme is; (2) identify a SPECIFIC enzyme in glycolysis that performs this function; and (3) identify the names of the organic substrate and product for the specific enzyme identified. Remember that the name of the category need not appear in the actual name of the enzyme. A. First enzyme category: kinase (answer (1), (2), and (3) B. Second enzyme category: dehydrogenase (answer (1), (2), and (3) C. Third enzyme category: isomerase (answer (1), (2), and (3)

a) List all possible factors that regulates metabolic reactions (glycolysis) and briefly explain them in full sentence.  b) How does cell overcome nonspontaneous reaction 1 and 3 in glycolysis? Support your answer in full sentence.

3) Read the situations below and indicate which of the four methods of enzyme regulation is occurring for each. a) The energy-carrying molecule ATP is made by the enzyme ATP synthase. Muscle cells use a lot of energy and also have higher amounts of the ATP synthase enzyme than many other cell types. General mechanism of enzyme regulation: S b) Prostaglandins are messenger molecules involved in the inflammatory response, as well as the perception of pain. They are synthesized from polyunsaturated fatty acid substrates by an enzym called cyclo-oxygenase. "Ibuprofen" is the active ingredient in a variety of anti-inflammatory medications such as Motrin® and Advil®. It reduces pain and swelling by binding to a hydrophobic channel in the active site of cyclo-oxygenase, blocking the polyunsaturated fatty acids from binding to the enzyme, and therefore stopping production of prostaglandins.
