Question

Which has more calories: 3 g of glucose, 3 g of lipids, or 3 g of proteins? why?

Why does the mitochondria produce more ATP than glycolysis for each molecule of glucose broken down

Answer 1

Answer) carbohydrates (glucose) provides 4 calorie per gram similarly protein also provide 4 calorie per gram but fat provides 9 calories per gram. So accordingly highest energy source will be fats but they slowly. Provide energy but carbohydrates are the instant source of energy.

Answer) as we in case of glycolysis intial step are energy investment ath in which the ATP is utilised at 1 and 2 phosphate addition and finally yeilds 7 ATP but in case of Krebs cycle and electron transport chain all the Highest energy sources like NADH2 AND FADH2 are converted in ATP 1 molecules of NADH2 forms 2.5 ATP AND FADH2 forms 1.5 ATP. SO THE YEILD OF ATO IN mitochondria is more as compared to glycolysis
