This is the process that releases energy by breaking down food molecules in the precence of oxygen

CELLULAR RESPIRATION

Explanation:

Cellular respiration is defined as the oxidation (break down in the presence of oxygen) of organic food substances within the cell leading to the release of energy, carbon dioxide and water.

It can be represented by the equation:

C6H12O6 + 6O2 --> 6H2O + 6CO2 + Energy (in form of ATP)

Thus, the main purpose of cellular respiration that takes place in a cell is to generate energy required by the whole body.

it provides an alternative energy pathway for the reaction to proceed.

a catalyst is a substance that speeds up the rate of a chemical reaction but is not consumed during the course of the reaction.

catalysts increase the rate of reaction without being used up. they do this by lowering the activation energy needed. with a catalyst, more collisions result in a reaction, so the rate of reaction increases. different reactions need different catalysts.

a catalyst works by providing an alternative reaction pathway to the reaction product. the rate of the reaction is increased as this alternative route has a lower activation energy than the reaction route not mediated by the catalyst.
