Write each of these four reactions, including all participants. i. ii. iii. iv.Question 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 26 During gluconeogenesis, whereby liver cells convert pyruvate to glucose, Fructose-6-phosphate (F6P) is converted to Glucose-6-phosphate (G6P).

Fructose-6-P ó Glucose-6-P > 1; exergonic > 1; endergonic < 1; exergonic < 1; endergonic

Draw a metabolic chart depicting the reactions of phase 1 of the glycolysis pathway, including metabolite names, enzyme names and cofactors. Chemical structures are not a requirement in this answer 2.3.raw a diagram of the reactions of mitochondria/ 8-oxidation of hexanoic acid (CH3-(CH2)4-COOH). Include activation and mitochondria/ transportation and the structures of the intermediatesQuestion 1: When the CAC is run in reverse by microorganisms that use it to fix carbon, the citrate synthase reaction is different and is catalyzed by an enzyme called ATP-citrate lyase. Write the reaction catalyzed by ATP-citrate lyase, then briefly (in one sentence) explain why the use of different chemistry (different from the ‘normal’ direction) makes sense here.
- Question 29 options: If 6 molecules of acetyl CoA were completely oxidized by the CAC, how many molecules of FADH2 would be produced?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.QUESTION 47 The role of oxygen gas in our cells is to accept electrons that come from NADH. produce CO2. react with glucose to split water. catalyze reactions in glycolysis. breakdown ATP.
- Question 9 - Under anaerobic conditions in the muscle, lactate dehydrogenase catalyzes the reaction converting pyruvate to lactate. What is the metabolic reason for this fermentation reaction? It is necessary to reduce pyruvate before it can be converted to acetyl-CoA and enter the citric acid cycle in muscle. NAD* must be replenished for glycolysis to continue. The reaction creates NADH which can produce additional energy in the electron transport chain. O Lactate is more oxidized than pyruvate.Question:- 33) Glucose-6-phosphate has different pathways that it can enter in the liver during the fed state. All of the following are possible except OA.) it is oxidized to acetyl CoA for fatty acid biosynthesis O B). it can enter the pathway for glycogen biosynthesis O c.) it is a substrate for glucose-6-phosphatase OD. )it is oxidized in glycolysis to provide energy for the bodyQuestion 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?)
