How do different substances have different amounts of calories?
Accordingly, why do different foods have different amounts of calories?
So part of the reason that foods have different calorie levels is that a usual serving of each food contains different amounts of the three classes of the energy-providing nutrients: carbohydrates, proteins and fats. Carbohydrates and proteins each provide 4 calories per gram for use as energy in the body.
Likewise, how are calories and ATP related? The amount of energy stored is about 7,300 calories for every mole of ATP formed. At the energy-requiring site, the last phosphate group in the tail is broken off and the energy in the bond liberated. Again, about 7,300 calories of energy per mole is released. In this way, ATP and ADP are constantly being recycled.
Correspondingly, is KCAL different from Cal?
The calorie is a unit of energy widely used in nutrition. The large calorie, food calorie, or kilocalorie (Cal, calorie or kcal) is the amount of heat needed to cause the same increase in one kilogram of water. Thus, 1 kilocalorie (kcal) = 1000 calories (cal).
