Perhaps you should define what you mean by certain types of sugar. In principle, everything you eat is broken down into it's basic components in your stomach, and from there they are absorbed into your blood stream. Things that are simpler to break down will be absorbed faster than more complex foods. For example, sugar is absorbed much faster than starch, even though the starch is broken down into smaller units of sugar.
What type of test are you doing, and what is it's purpose?
When you say greater efficiency, what do you mean? Glucose is used by your body to provide energy(the glucose is broken down, and energy is produced), other sugars such as sucrose have to be converted to glucose before they can be used, so glucose will be metabolized faster than other sugars. But the sugar that is most widely used to make things sweet is sucrose (because it is much sweeter than glucose).
An apple is better (imo) than a donut, because the apple contains starch (which is essentially made up of units of glucose). The donut will give you a quick burst of energy but it will last for a short while and then the sugar will disappear from your blood. The energy from the apple will last much longer. And in addition apples contain other stuff that is healthy.
