What are the reasons that a jelly baby gives you more energy than a similar piece of carrot?

The Jelly baby doesn't actually have more energy, although it seems as if it does as you feel quite energetic after eating one, more so than after eating a carrot. You actually get more energy from a carrot as the jelly baby gives you a small burst of energy, but then you feel deflated as the energy is gone but the carrot gives more energy, slower than a jelly baby-it lasts longer as instead of one big burst, it gives smaller bursts of energy throughout a longer period of time-so lasting longer.
