Definitions:

Efficient Process

A procedure characterized by minimal waste and maximum productivity, effectively achieving its intended result with the least amount of time and resources.

Chemiosmosis

The movement of ions across a semipermeable membrane, down their electrochemical gradient, which is used by cells to generate ATP during processes like photosynthesis and cellular respiration.

Glycolysis

The metabolic pathway that breaks down glucose into pyruvate, releasing energy and pyruvic acid, the first step in cellular respiration.

Citric Acid Cycle

A set of chemical transformations that enable aerobic entities to produce energy, through the oxidation of acetate from carbohydrates, fats, and proteins into carbon dioxide.
