Definitions:

Glycolysis

A metabolic pathway that breaks down glucose into pyruvate, releasing energy and forming ATP and NADH, occurring in the cytoplasm of cells.

Citric Acid Cycle

A series of chemical reactions used by all aerobic organisms to generate energy through the oxidation of acetate derived from carbohydrates, fats, and proteins.

Preparatory Reaction

A phase in cellular respiration where pyruvate from glycolysis is converted into acetyl-CoA, enabling the next steps in energy production.

Cellular Respiration

The metabolic process in which cells break down sugars to generate energy in the form of ATP, involving pathways like glycolysis and the Krebs cycle.
