Krebs cycle (aka citric acid cycle, aka tricarboxylic acid cycle)

Because it goes around and around as in a unicycle wheel.

The conguate base of citric acid - citrate - is an important intermediate in the cycle. This is where the name "Citric Acid Cycle" comes from.

It is also known as the Tricarboxylic Acid Cycle - as it involves 3 carbon acids, or the Krebs Cycle after Hans Adolf Krebs - who developed the complexities of the cycle.

The net inputs for citric acid cycle are Acetyl CoA, NADH, and ADP. The Net outputs for the citric acid cycle are ATP, NAD, and carbon dioxide.
