High concentration of NADPH increases the rate of the pentose phosphate pathway by stimulating glucose-6-phosphate dehydrogenase. i. True ii. FalseQuestion 1: The overall process enabled by the glyoxylate cycle is: (2acetyl-CoA) + (NAD+) + (2H2O) → (succinate) + (2CoA) + (NADH) + (2H+) Dissect this process further by writing down all of the reactions that are actually involved in making one succinate from two acetyl-CoA units. Show chemical structure for all intermediates.QUESTION 1 a. John has just taken his Lunch meal, after which he is going to takes his Daily soccer practice match in the next 30 min, how will glycolysis operate/work in such conditions or be applicable b. How will oxidative phosphorylation work in sickly John who usually practice daily in soccer? Make possible scenarios c. Enzymes are critical in the metabolism of most most organic compounds, actually 30% of reactions are catalysed by them. How would the inactive enzymes (Sickness) in electron Transport Chain compromise the fat breakdown in the body.
- Need help, please. For the scenario below relating to Glycogenolysis, please explain how glucose release would be affected. Would it increase, decrease, or result in no change when compared to “normal” conditions? In addition, please identify which enzyme or reaction is affected and why. Scenario: free inorganic phosphate is chelatedCan you explain the oxidation phosphorylation process and its protein complexes? Thank you!Question 1: Part a: Assume that the standard free energy of ATP hydrolysis is -31 kJ/mol. Assume the following values for the standard free energy changes of the four reactions: HK -16.7 kJ/mol; PFK -14.2 kJ/mol; PGK -18.9 kJ/mol; PK -31.7 kJ/mol. (from bio.libretexts.org). Use these values to compute the standard free energy of hydrolysis (releasing Pi) of i. glucose 6-P ii. fructose 1,6-bis-P iii. 1,3-bisphosphoglycerate iv. phosphoenolpyruvate Part b: Which of these four compounds is the strongest phosphoryl donor?______________ Which is the weakest?__________________ Part c: The phosphoglycerate kinase reaction is favorable by -18.9 kJ/mol in the glycolytic direction, as stated above. In gluconeogenesis, this step is simply reversed; i.e. it is not one of the three steps in gluconeogenesis that is driven by using different chemistry than that of glycolysis. How can this be? (Be specific: what specific factors could enable reversal of this step?)
