That is called "Glycolysis". See the link for an animation.
The process of breaking down food to release energy is called "Digestion".
No, photosynthesis is the absorbtion of CO2, H20 and UV light in order to produce O2 and sugar molecules.
Breaking bonds produces energy making it an exothermic process.
Metabolism
The formation of chemical bonds releases energy. It is an exothermic process. The breaking of chemical bonds takes energy. It is an endothermic process.
It has a universal function. That is to produce energy
They produce energy through a process known as cellular respiration. In it, glucose is converted into energy.
Producers are plants. They produce energy through the amazing process of photosynthesis.
No. Water is essential in the process of metabolizing nutrients to produce energy, but water does not provide any energy, itself. Another way of looking at it is this: energy is obtained by breaking down molecules in reactions which release energy. Water molecules cannot release energy when they are broken down--on the contrary, breaking a water molecule consumes a significant amount of energy.
Digestion
Digestion.
Catalase helps to begin breaking down sugar to finally produce energy.
