Diagram of the eight-step tricarboxylic acid cycle showing the sequence of metabolites from acetyl CoA through citrate, isocitrate, alpha-ketoglutarate, succinyl CoA, succinate, fumarate, malate, and oxaloacetate, with arrows indicating the flow of reactions and production of ATP, NADH, FADH2, and CO2.

Diagram illustrating metabolism with two sections: anabolic reaction on the left shows energy used to build larger molecules from smaller ones, while catabolic reaction on the right shows larger molecules breaking down into smaller molecules with energy released.

A biochemical pathway diagram showing the catabolism and biosynthesis of glucose and glycogen, with glucose breakdown reactions on the left and synthesis reactions on the right, interconnected by labeled arrows and chemical intermediates.

A metabolic pathway diagram for Escherichia coli showing how various nutrients-including sugars, fats, glycerol, and amino acids-are broken down into intermediates like pyruvate and acetyl-CoA, leading to the production of energy and other metabolites such as lactate, glutamate, and succinate. Arrows indicate the flow of metabolites between compounds, with key nutrient sources and products highlighted in colored boxes.
