Carbon and hydrogen
Fuel cells are energy sources that produce electricity by chemically combining gases or liquids into fuel. They work through an electrochemical reaction that converts the chemical energy of the fuel into electrical energy, making them an efficient and clean alternative to traditional combustion-based power generation.
Batteries and fuel cells are energy sources that use chemical reactions to produce electrical energy. In batteries, chemical reactions within the cells generate an electrical current, while in fuel cells, hydrogen and oxygen react to produce electricity, heat, and water.
To break down sugar and produce useful energy, the cells need many things, but most importantly they need ENZYMES.
Photosynthesis is the process that uses carbon dioxide and the sun's radiant energy to produce chemical energy in the form of glucose. This process occurs in the chloroplasts of plant cells and involves the conversion of light energy into chemical energy.
The process of combining oxygen with food to release energy is called cellular respiration. This process takes place in the mitochondria of cells and involves the breakdown of glucose molecules to produce ATP, the energy currency of the cell.
A chemical reaction that happens in every cell to break down sugar
Chemical energy can be transformed into electrical energy through a chemical reaction that generates an excess of electrons. These electrons can then flow through a conductor, such as a wire, creating an electric current. This process is utilized in batteries and fuel cells to produce electrical energy.

The chemical energy to produce ATP (adenosine triphosphate) primarily comes from the breakdown of glucose through the process of cellular respiration. Glucose is metabolized into ATP through a series of chemical reactions that occur in the mitochondria of cells, where energy is stored in the form of ATP molecules.
The process of combining oxygen and food to produce energy is called cellular respiration. During this process, cells break down glucose molecules in the presence of oxygen to produce ATP (adenosine triphosphate) which is the energy currency of the cell. Carbon dioxide and water are byproducts of this process.
Some examples of converting chemical energy to electrical energy include batteries, fuel cells, and voltaic cells. In batteries, chemical reactions occur to produce a flow of electrons, generating electrical energy. Fuel cells use hydrogen and oxygen reactions to produce electricity, while voltaic cells generate electricity through redox reactions between two different metals.
