Question
Chapter 27, Problem 6P
Interpretation Introduction
Interpretation : Food consumed by the lady in 40 years should be calculated.
Concept Introduction : The amount of energy required to balance the energy loss to maintain the body size, composition, and level of physical activity is termed as energy requirement. Energy in the human body is derived from macronutrients, such as carbohydrates, fats, ethanol, and proteins.

- Triacylglycerols, with their hydrocarbon-like fatty acids, have the highest energy content of the major nutrients. (a) If 15% of the body mass of a 70.0 kg adult consists of triacylglycerols, what is the total available fuel reserve, in kilojoules and kilocalories, in the form of triacylglycerols? Recall that 1.00 kcal = 4.18 kJ. (b) If the basal energy requirement is approximately 8,400 kJ/day (2,000 kcal/day), how long could this person survive if the oxidation of fatty acids stored as triacylglycerols were the only source of energy?

As a result, all three amino acids are considered [glucogenic/ketogenic/metagenic]. The carbon of urea comes directly from [carbon dioxide/a-carbon of an amino acid/glucose].
