This energy is derived from the chemical bond energy in food molecules, which thereby serve as fuel for cells. The first step is the enzymatic breakdown of food molecules in digestion, and the second step that converts glucose molecules is called glycolysis.
chemical energy
The mitochondria in a cell convert food cells into energy. The cell uses that energy to kickstart necessary reactions.

Chloroplasts contain chlorophyll molecules which absorb the sun's energy and convert it to chemical energy which can be used to fuel chemical reactions in the cell.
Any outside stimulus or necessary action can trigger a chemical reaction in a cell. Indeed, just maintaining the life of the cell has huge numbers of chemical reactions. They are why we live.An example of outside stimulus: dopamine being released in the brain to induce "happiness."An example of necessary action: thermoregulation causing a pH change to absorb energy (lowering heat) or giving off energy (to increase heat).
Mitochondia
In the cytoplasm, because that is where the chemical reactions happen.
Chemical Energy, stored in the atomic and molecular structures of chemicals, is important as it is released and used in cells for certain processes via chemical reactions, in other words, the chemical energy and the molecules involved set the stage for such chemical reactions.
Mitochondrion is the cell organell that is directly a part of production. This is a cell of energy.
When two molecules react within a cell, their atoms are rearranged. This releases or consumes energy.
