There are four stages: glycolysis, the link reaction, the Krebs cycle and oxidative phosphorylation.

GLYCOLYSIS

Glycolysis is the process in which one glucose molecule is broken down to form two molecules of pyruvic acid (also called pyruvate). The glycolysis process is a multi-step metabolic pathway that occurs in the cytoplasm of animal cells, plant cells, and the cells of microorganisms.

THE LINK REACTION

The link reaction generates one NADH/pyruvate, and two NADHs/glucose. ... The Krebs cycle generates more NADH/glucose than any other phase of cellular respiration. No. Electron transport chain doesn't produce NADH: it consumes it.

THE KREB'S CYCLE

The Krebs cycle is a series of chemical reactions used by all aerobic organisms to generate energy through the oxidization of acetate—derived from carbohydrates, fats, and proteins —into carbon dioxide. Theoretically there are several alternatives to the TCA cycle, but the TCA cycle appears to be the most efficient.

OXIDATIVE PHOSPHORYLATION

Oxidative phosphorylation is the metabolic pathway in which cells use enzymes to oxidize nutrients, thereby releasing the chemical energy stored within the nutrients in order to produce adenosine triphosphate. In eukaryotes, this takes place inside mitochondria.
