Question

A pound of butter contains more usable energy than a pound of sugar for a human because
A Sugar contains much more water than butter
B. A fat molecule has more carbon-hydrogen bonds than a sugar molecule
C. The butter is an animal product, where as the sugar is a Plant Product
D. There is much more waste in digestion and absorption of sugar than of butter

Answer 1

Hint:- A pound of butter contains more usable energy than a pound of sugar. Butter contains fat molecules and sugar has carbohydrates.Fat has a low ratio of oxygen and hydrogen compared to carbohydrates.

Complete step-by-step solution:-Butter is the source of fat as it contains fat molecules,and sugar is the source of carbohydrates .Fats are the slowest energy source. So these are the most energy effective source of food .Each gram of any fat, supplements the body with about 9 calories of energy which is greater than 2 times that the energy obtained from carbohydrates and proteins.Fat has low ratio of oxygen and hydrogen comparison to carbohydrates in sugar.Therefore fat has more carbon hydrogen bonds than carbohydrates.
As fat gives the energy two times than the energy from the carbohydrates, fats are an effective energy form that the body accumulates.The excess energy the body stores is in the form of fat. If sugar is consumed more as it has more carbohydrates it is very difficult to get broken down and digest.

Note:- So Butter is the good source of fat and the body accumulates fat as the source of energy for future usage. Butter has a low oxygen and hydrogen ratio so has more carbon hydrogen bonds.Sugar are complex carbohydrates which take time to digest and have less carbon hydrogen bonds.
