Cellular RESPIRATION
Cellular Respiration is the process by which each cell is broken down into organic compounds, which then releases energy and creates adenosine triphosphate (ATP). ATP is created by the formula ADP + Pi -->ATP.
Cellular Respiration consists of 4 steps:
1. Glycolysis
2. Form of Acetyl Co-enzyme
3. Kreb's Cycle
4. Electron Transport Chain
Cellular Respiration starts out with Glucose (a monosaccharide).
Then, in a process called Glycolysis, the glucose is broken down, producing a net gain of 2 ATP. Also, in this process, 2 molecules of NADH are created.
Glycolysis starts in the Glucose, and occurs in the Cytoplasm

Which produces Pyruvates (Or pyruvic acid, which supplies energy to living cells through the citric acid cycle) and can be used in both Anaerobic and Aerobic Respiration.

Aerobic Anaerobic
Aerobic Respiration is a process that requires oxygen
Anaerobic Respiration is a process where oxygen is not required
Anaerobic processes, such as Fermentation (Process where electrons from nutrients are transferred to molecules brought from the breakdown of the same nutrients) are a set of pathways that use pyruvic acid is converted into organic molecules in the cytosol. Fermentation does not produce ATP, but does regenerate NAD+, which helps Glycolysis continue operating.
Aerobic processes can produce up to 38 ATP molecules, all from the oxidation of one molecule of Glucose. During Aerobic respiration, oxygen accepts both electrons and protons from the ETC. As a result of Aerobic Respiration, oxygen is converted to water.
