Q25 - The urea cycle and nitrogen disposal
Pinned
The correct answer is E) Urea cycle.
The urea cycle happens almost entirely in the liver, where ammonia from protein breakdown is turned into urea for the kidneys to get rid of.
The others happen all over the body: glycolysis in every cell, the Krebs cycle in nearly every cell with mitochondria, and β-oxidation and transamination in many tissues, especially muscle.
