Carbohydrates.
The chief food energy storing molecule used by organisms is carbohydrates. Glycogen is a carbohydrate storage molecule which is employed by animals.
The main source of energy is from the sun.
The carbohydrates are the main source of energy from the food you eat, becausethey are most easily converted to useable energy. Fats are the second energy source used.Proteins are the third and most difficult source to be converted to energy.
The source of chemical energy for the muscles are compounds. this will also go with gas, food, and e.t.c.
You are probably looking for the "Citric Acid Cycle" sometimes known as the "Krebs Cycle" .
autotroph.
The energy source for flagella and cilia is the ATP (adenosine triphosphate) molecule used throughout the cell. ATP gets its energy from glucose and glycerol, that is from food.
Glucose is considered a very important molecule for living beings because it provides us energy & we use most of the energy in the form of glucose(the ultimate source of energy. bhuvan sorout
I think you are referring to the mitochondria. They release energy stored in food.
ATP
The source of energy for plants is sunlight.
In most food webs the Sun is the ultimate source of energy. Some food webs start with chemotrophs and in those cases the source of the energy are chemicals often from underwater volcanoes.

from food
chemical to machanical energy
The food is first broken down into its simplest forms. The cellular organelle know as the mitochondria receives it and breaks it down even more producing ATP. ATP is the main energy source for the cell.
Yes fats are the most calorific energy source.
