The scientific equation C6H12O6 + 6O2 —> 6CO2 + 6H2O + Energy is the chemical reaction for respiration within a cell. Respiration is defined as the oxidation of sugar by organisms. It occurs in plants and animals and, in most cases, releases energy that is required for other processes in the cell.
By breaking down the components of the equation for this chemical reaction, a person can easily see the components that are involved. Glucose plays a big part in a cell's respiration, and it is represented by the molecular formula C6H12O6. Oxygen is required for the respiration process to take place, and that is represented by the formula 6O2. When glucose and oxygen are combined, the chemical reaction of respiration takes place. The glucose becomes oxidized and loses electrons, giving the formula 6CO2; the oxygen is reduced as it gains water, giving the formula 6H2O; and energy is gained in the process.
In oxidizing the glucose, the cell takes the energy from this chemical process and uses it for ATP synthesis. The ATP synthase is considered to be the most important carrier of energy in a cell. It captures energy, then uses that energy to fuel other processes within the cell. While most are formed during respiration, some are also made during photosynthesis.
