If you ate a samples of the different carbohydrates seen here, how would the available energy differ from each source and why? a) the simple sugars would have less energy than the complex sugars, because the molecules are smaller. b) the simple sugars would have more available energy, because they are small molecules and are easy to break down. c) the complex carbohydrates would produce the most energy, because they have a high c: h ration and relatively little oxygen. d) all of the carbohydrates would produce about the same amount of energy, as they all have a large amount of oxygen atoms.
