- During a 20-minute workout, a person burns 350 calories. What is the number of grams of glucose undergoing glycolysis in muscle cells with ample supply of oxygen? NADH in muscle cells is transported via the glycerol phosphate shuttle (which byhpasses Complexes I and II of the ETC). The human ATP synthase has 8 c subunits. Take note: Molar mass of glucose is 180 g/mol 1 calorie = 4.184 J phosphorylation potential in muscle cells is ~55 kJ/molCalculate the ATP yield for the full catabolism of a phospholipid containing ethanolamine, C18:3 Δ9, 12, 15 and oleic acid. Include any ATP “expenses” or “income”. This will be a complex problem—neatly show your work and justify your choices.What is the total ATP produced from complete oxidation of 10 molecules of glucose asumming that the shuttel used is the glycerol-3-phosphate shuttle?
