This is from my general knowledge; I'm not an expert and I didn't look this up recently:Carbohydrates. The muscles burn blood glucose first, then they draw upon sugar stored in the muscle tissue itself, then they burn the fat, then they start eating themselves--but that only happens when they're being overexerted to the extreme and during starvation. That's my understanding anyway. Again, I'm no expert.
If this is for a simple school question, carbohydrates is probably the desired answer.

Sugars and fats :)

Heat energy.
Solar energy
Nuclear is the most dangerous type of energy
The sun light is the most important because while it cannot be used by humans directly, it can be used by plants to grow and provide food.

All complex cells contain mitochondria.

A greenhouse uses solar energy to heat and provide light.
Substances in Biology that provide energy as the result of a chemical change are called?
Type your answer here... active transport
It depends on the type of carbohydrate. Simple carbohydrates (or sugars), such as glucose and fructose, are absorbed into the bloodstream and provide an immediate energy boost, and are the most quickly turned into energy. Other carbohydrates, such as starch, take more time to digest and are probably similar energy wise as protein or fats. However, as far as containing the most energy in a given amount, fats beat all carbohydrates and proteins by far.
