The changing of substances to other substances by the breaking of bonds in reactants and the formation of bonds in products

This statement refers to a chemical reaction

Explanation:

A chemical reaction occurs when certain substances are transformed into others. For this to happen, the bonds between atoms and molecules must be broken and must be reestablished in another way. In summary, a chemical reaction is the change of substances to other substances by breaking bonds in reagents and forming bonds in products.

Since these bonds can be very strong, energy, usually in the form of heat, is needed to initiate the reaction. The new substances have different properties than the original substances (reagents).

thinking it would be physical characteristics

cellular respiration oxidizes food into energy in the form of atps.

glycolysis (6 c hexose) > 2x atps are used > 6c hexose biphosphate > 2 x 3c triphosphate >

2 x 3c pyruvate (2x nadh produced from nad) and (4x atp produced)

pyruvate actively pumped mitochondrial matrix.
