Glycolysis: There are two important ways a cell can harvest energy from food: fermentation and cellular respiration. Both start with the same first step: the process of glycolysis which is the breakdown or splitting of glucose (6 carbons) into two 3-carbon molecules called pyruvic acid. The energy from other sugars, such as fructose, is also harvested using this process. Glycolysis is probably the oldest known way of producing ATP. There is evidence that the process of glycolysis predates the existence of O2 in the Earth's atmosphere and organelles in cells: * Glycolysis does not need oxygen as part of any of its chemical reactions. It serves as a first step in a variety of both aerobic and anaerobic energy-harvesting reactions. * Glycolysis happens in the cytoplasm of cells, not in some specialized organelle. * Glycolysis is the one metabolic pathway found in all living organisms.
36 ATP are produced during Aerobic Cellular Respiration.
It is used in a very large variety of otherwise non-spontaneous reactions within the cell. Almost everything that does not instead use NADH or FADH.

Krebs Cycle .
The Mitochondria
Majority of ATP molecules are produced in mitochondria, via F1-F0 particles, through electron transport system.
The majority of ATP molecules are produced in the mitochondria during aerobic cellular respiration, which can produce about 36 molecules of ATP. In contrast, anaerobic respiration, which occurs in the cytoplasm, produces a net gain of only 2 ATP molecules.
72 molecules of ATP are produced .
In the Electron Transport System
2 ATP molecules are produced in anaerobic respiration (where there is no oxygen), while in aerobic (where there is oxygen) respiration, 36 ATP molecules are produced.
The mitochondria is the site of aerobic respiration and is where the majority of the cells energy is produced.

Carbon dioxide, water and energy are produced by aerobic respiration. The word equation for aerobic respiration is: Glucose + oxygen --> carbon dioxide + water + energy Energy and lactic acid are produced by anerobic respiration The word equation for anaerobic respiration is: Glucose --> energy + lactic acid
