Cellular rerspiration is the process of breaking down glucose into energy and other products.
Anaerobic respiration: glycolysis, and either alcoholic fermentation, or lactic acid fermentation Aerobic respiration: Citric acid cycle (Krebs cycle), electron transport chain
In glycolisis, the 6-carbon sugar, glucose, is broken down into two molecules of 3-carbon molecules called pyruvate
In alcoholic fermentation, pyruvic acid is broken down into ethanol and carbon dioxide.
In lactic acid fermentation pyruvate acid from glycolysis is reduced into lactic acid by NADH, which oxidizes into NAD+.
The citric acid cycle (Krebs Cycle) is a series of chemical reactions used by all aerobic organisms to generate energy through the oxidtion of acetate
The electron transport chain is a series of comounds that transfer electrons from electron donors to electron acceptorsvia redox reaction and couples its transfer with transfer of protons (H+ ions) across a membrane.
