This document outlines the key steps and molecules involved in glycolysis and the citric acid cycle, two important metabolic pathways that break down glucose to extract energy in the form of ATP. Glycolysis breaks down glucose into pyruvate, extracting some energy in the form of ATP and NADH. Pyruvate then feeds into the citric acid cycle, where it is further oxidized, extracting more energy in the form of ATP, NADH, and FADH2, and producing carbon dioxide as a byproduct. These pathways are central to energy production and biosynthesis in cells.
