Cellular respiration produces ATP. ATP is used for releasing energy. However, not all the energy in ATP is going to be able to be used for cellular activities.

Glucose is the initial source of energy for glycolysis (the first step in cellular respiration).Respiration produces ATP, which is a form of energy that the cell can use.
Glycolysis is the first pathway involved in the breakdown of glucose. It produces 2 ATP per glucose molecule. The Krebs Cycle and oxidative phosphorylation together make up oxidative respiration and synthesize the bulk of ATP in the human body.
they perform cellular respiration inculding-glycolysis-the Krebs cycle- going through the electeron transport chain-going through the ATP Synthasewhich creates energy for the cell (ATP)
The single most important biochemical especially to us is " Cellular respiration ". Because this is how we derive energy from what we eat and used in some metabolic reactions and muscle contraction, nerve impulses.or in simple "Cellular respiration" is process from which the organisms can derive energy from the metabolic reactions.cellular respiration is starts from glucose. During cellular respiration one mole of glucose and six moles of molecular oxygen going to produce six carbon dioxide, six water molecules, and energy and 38 ATP's ( energy currency for biological system )Under cellular respiration :1) Glycolysis/ anaerobic cellular respiration ( breaking up glucose; gluc= sweet, ose = sugar ): It occurs completely under the absence of oxygen. so it this is called " anaerobic cellular respiration ".where in Glycolysis the glucose molecule need 2ATP's and generates 2ATP's so it generates a net of 2 ATP's.the byproducts of glycolysis that re-engineeredand enters in to aerobic( requires oxygen ) cellular respiration process called ;2) Krebs cycle( aerobic cellular respiration ) : Krebs cycle generates another 2 net ATP's. This 2ATP's produces NADH.3) Electron transport chain/ ETC ( aerobic cellular respiration ) : ETC generates 34 ATP's by using the NADH which are produced from the ATP in Krebs cycle.this cycle requires oxygen so aerobic respiration.that's about cellular respiration and aerobic process ( 2nd and 3rd ).Here some important thing is some of the byproducts of the glucose ; instead of going in to Krebs and ETC cycle enters into a process called Fermentation and produces alcohol and lactic acid.( Yeast= alcohol, called alcohol fermentation)( Humans= lactic acid) .
Cellular respiration is more efficient than fermentation. Cellular respiration produces approximately 36-38 ATP molecules, while fermentation produces only 2 ATP, which is a significant loss in usable energy.
I guess your question implies to "oxygen" when you mean "respiration". As said before, anaerobic bacteria such as sulphate reducing bacteria (Desulfovibrio as an example) use sulphur to make ATP or energy.
We just learned about this in College Bio... Cellular Respiration makes ATP which is a form of energy. Depending on how you look at it, the cell makes about 38 ATP per glucose, but only nets 36. Some also say that it's closer to 30 because you need some activation energy to get the process going, and some ATP are lost during the cycle.
I'm going to assume that you mean the process of makingATP in the mitochondria. If that's what you meant, then the answer is "ATP Synthesis"
Virtually all oxygen using organisms have cellular respiration going on. C.R. is the breakdown of glucose using oxygen to release energy as ATP - so anything - plants, animals, single celled organisms - that take in oxygen and glucose are going to do CR. Organisms that can't tolerate oxygen or run out of oxygen (like your muscles during a strenuous workout) will do fermentation instead. Fermentation will get the job done but respiration releases much more energy per molecule of glucose.
Cellular respiration is the process by which energy is released from food molecules and stored in molecules of ATP, the energy currency of the cell. Without ATP cells could not function.
