During rest and normal activities by the body fats contribute the biggest percentage as a source of energy followed by carbohydrates and the proteins contributing the least amount of energy. However, during strenuous exercises the body mostly uses energy from the stored carbohydrate stored in the muscles in the form of glycogen. Energy may be partially obtained from blood sugar, fatty acids in the blood and also triacylglycerols in the muscles.Therefore its not true that during intense exercise fat stores are used as a source of energy.
The high energy molecule formed at the end of cellular respiration is B. ATP.
Atom is the
most basic unit of matter. They are the general term used to describe pieces of
matter. But a different kind of atom makes up an element. A combination of atom of different elements
creates a molecule. For example, you have water; it has a chemical formula of
H2O. If you separate H from O, you have two atoms. Two atoms for hydrogen and
one atom for oxygen. However, they are of different elements. And when you
combine them to form H2O, you create a molecule.
