EASY TO UNDERSTAND BASICS ABOUT CELLULAR RESPIRATION:

Respiration is the process by which cells obtain energy from glucose. During respiration, cells break down simple food molecules, such as sugar, and release the energy they contain. Respiration is carried out continuously by plant cells, as well as animal cells. This process begins in the cytoplasm, where molecules of glucose are broken down into smaller molecules. Oxygen is not involved, and only a small amount of energy is released. Next, the process moves on to the mitochondria, where the small molecules are broken down into even smaller molecules. These chemical reactions require oxygen, and they release a great deal of energy. This energy is still stored in the form of chemical energy, but now it is stored in molecules that are readily used by the cell. The three final products are carbon dioxide, water, and energy.

Cellular respiration is a cellular process that requires oxygen and gives off carbon dioxide in order to obtain energy for the organism. That's a brief meaning so see the Related Link below for more info.

In brief, there are 3 stages: Glycolysis, the Kreb's Cycle, and Oxidative Phosphorylation (or Electron Transport Chain). Cellular respiration takes place near or in the mitochrondria, an organelle in all eukaryotic cells.

In Glycolysis, a sugar is taken in and, through a bit of energy stored in Adenosine Triphosphate (ATP), it gives off some electrons which are stored, and it splits into Pyruvic acid.

In the Kreb's Cycle, the Pyruvic acid gives off more electrons and cycles through, some of it becoming carbon dioxide.

In Oxidative Phosphorylation (Electron Transport Chain), the stored electrons "pump" hydrogen cations (positive ion) to one side of the inner mitochondria membrane. Due to the high concentration, the hydrogen cations flow back through a protein that makes a lot of ATP. For every sugar molecule, it makes about 60 of these. The oxygen is taken in here to take care of the hydrogen ions- it becomes water.
it converts energy in food into a more usable form!
The chemical process that generates most of the energy in the cell, supplying molecules needed to make the metabolic reactions of an organism run.
