What is homestasic enzyme?
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.
