11. Studies have shown that long chain fatty acyl-CoAs inhibit ACC and FAS via feedback inhibition . 12. Pepsin also undergoes feedback inhibition ; a product of protein digestion slows down the reaction by inhibiting pepsin. 13. These isoenzymes all have the ability to help regulate synthesis of DAHP by the method of feedback inhibition . 14. As such, E1o is inhibited by both NADH and Succinyl-CoA via non competitive feedback inhibition . 15. Normally, adrenal steroids then signal their presence to the brain to moderate ACTH levels ( feedback inhibition ). 16. He invented the chemostat, discovered feedback inhibition , and was involved in the first cloning of a human cell. 17. All the enzymes in this biosynthetic pathway are subject to regulation via feedback inhibition and / or repression at the genetic level. 18. H 1 causes an increase in PIP 2 hydrolysis, H2 stimulates gastric acid secretion, and H3 mediates feedback inhibition of histamine. 19. At high concentrations of lactate, the enzyme exhibits feedback inhibition , and the rate of conversion of pyruvate to lactate is decreased. 20. If there is no feedback inhibition , such as suppressors of cytokine signaling proteins in the system, that would cause giantism in mice.
