Using the TOTAL carbohydrate per one serving, please calculate the number of ATP

Question

Using the TOTAL carbohydrate per one serving, please calculate the number of ATP molecules that can be synthesized from 1 serving’s worth of the total carbohydrates. Once you calculated the number of ATP molecules for 1 serving, you can then calculate the TOTAL serving you usually consume. IN YOUR calculations, use the molecular weight of total carbohydrates to be 343.00 Daltons or 343.00grams/mole

Remember: 1 NADH= 2.5 ATP molecules and 1 FADH2 = 1.5 ATP

The food chosen is a can of Coke: Total Carb is 39 grams

Explanation / Answer

One molecule of glucose gives 36 ATP molecules.

The molecular weight of total carbohydrates to be 343.00 Daltons or 343.00grams/mole

can be considered as sucrose (molar mass = 343 gm/mol)

Sucrose is broken down to glucose and fructose.ATPs obtained from thse two molecules will be the same.

So one molecule of sucrose will give 72 ATP molecules.

The food chosen is a can of Coke: Total Carb is 39 grams.

therefore moles of total carbs = 39/343 =0.1137 moles

no of molecules of total carbs = 0.1137 x 6.023 x 10^23

= 6.84 x 10^22 molecules

1 molecule gives 72 ATP molecules

therefore 6.84 x 10^22 molecules will give 4.93 x 10^24 ATP molecules
