The energy from cellular respiration comes from food and air. The reactants first cellular respiration are oxygen and glucose. Glucose is a form of sugar and comes from food, and oxygen is found in air.
The main reactants or cellular respiration, as stated above, are oxygen and glucose.
During the first stage of cellular respiration, which takes place in the cytoplasm, a small amount of energy is produced when glucose is broken down into smaller particles.

Conservation of Energy:
As a projectile is launched into the air KE is at its maximum. As the projectile gains altitude PE becomes greater than KE. At the top of its arc, PE is at its maximum. The whole cycle reverses itself on the way down.
        
             
        
        
        
B, osmosis is the movement of water across a semi-permeable membrane according to the gradient of concentration. The water moves to were the concentration of  solute is higher, that way the solute concentration is equalized.
