Enzyme Kinetics
... Enzymes are large protein molecules which act as biological catalysts – they speed up reactions in the body by reducing the activation energy of the reaction. The molecule on which an enzyme acts is called a substrate, and the place on the enzyme where the substrate binds is called the active site. ...

... Some enzymes are synthesized in active form and require no chemical groups for activity other than their amino acid residues. Other enzymes are produced in an inactive form due to either: - Presence of excess polypeptide in their structure and is converted to active form after deletion of this part. ...

Temperature Homeostasis (thermoregulation)
... In this reaction surplus amino-acids are converted to urea, ready for excretion by the kidney. Ammonia is highly toxic, and stops the Krebs cycle; urea is less toxic than ammonia, so it is safer to have in the bloodstream. The disadvantage is that it “costs” 3 ATP molecules to make one urea molecule ...
