Question:
What is homestasic enzyme?



Replies:
Hi Ghazal,

Thanks for the question. A homeostatic enzyme is an enzyme that is necessary for homeostasis, which is the maintenance of a constant internal environment inside an organism. Homeostatic enzymes are also referred to as "housekeeping enzymes". An example of a homeostasis enzyme is COX-1 (cycloxygenase-1). COX-1 is present inside the cells that line your stomach. COX-1 is necessary for cell growth and signalling. If COX-1 is disrupted, ulcers can occur. This is what happens when one takes too much aspirin over a long period of time.
