When molecules are broken down the energy is released from the outer electron shells of the various elements involved.
Energy harvested from organic molecules is contained in the chemical bonds within those molecules. This energy is released through the process of cellular respiration, where organic molecules are broken down and the energy is used to produce ATP, the cell's primary energy source.
Carbohydrates are the food molecules that can be broken down to provide energy for organisms. During digestion, carbohydrates are broken down into glucose, which is then used by cells to produce ATP, the primary form of energy used by the body.
The type of energy released when glucose is broken down is chemical energy. This energy is stored in the bonds of the glucose molecule and is released when those bonds are broken during cellular respiration to produce ATP (adenosine triphosphate) for cellular functions.
Food molecules are broken down to release energy by the process of cellular respiration. In this process, glucose and other nutrients are oxidized within the cells to produce ATP, which is the main energy currency of the cell. This occurs in the mitochondria of the cell through a series of metabolic reactions involving enzymes.
Sorry if I have misunderstood the question but I think your asking what is formed in respiration? This is where oxygen and hydrogen are used to turn Glucose (C6H12O6 or Sugar) into ATP. The process is massively complicated but around 30 ATP molecules is a good out put for arobic respiration. *ATP molecules are the energy form which our body uses to do everything.
In fermentation, glue close molecules are broken down, and energy is released.

Energy is required when organic molecules are synthesized because this process involves building complex molecules which requires input of energy. When organic molecules are broken down, energy is released because the breaking of bonds releases stored energy from the molecules. This energy can be used by the cell for various cellular processes.
Starch molecules can be broken down into glucose molecules when energy is needed. Glucose is a simple sugar that can be easily converted into energy by cells through the process of cellular respiration.
That energy is stored in ATP. ATP is the currency of energy.
Resperation
Digestion is necessary because for energy from the food to be released and carried into the cells in our body the food must be broken down into soluble molecules for it to diffuse into the cells. Then energy is released during respiration.
nutrient molecules are broken down
They are broken down into simpler molecules by the digestive system so they can be absorbed into the bloodstream.
Chemical energy is stored in sugar molecules. This energy is released when sugar is broken down in a process called cellular respiration, allowing cells to produce energy for various biological processes.
energy
The mitochondria releases energy from food molecules. This is where all things are broken down and turned into energy for the cell.
