Summary Introduction
To explain:
The negative feedback in thermoregulation differs from feedback inhibition in an enzyme catalyzed biosynthetic process.
Introduction:
Negative feedback occurs when the end product of an enzyme interferes or decreases the effect of the same enzyme that produced it. The feedback inhibition mechanism is the cellular process in which the end product of an enzyme inhibits the production of the same enzyme that produced it. By this process there is the maintenance of the amount of enzyme required. Both processes help in the regulation of the

Q1: Why is it important that enzymes are not permanently altered when they bind with substrate molecules? Q2: How would a higher temperature or higher salt concentration make it more difficult for an enzyme to function effectively? Q3: If a cell was unable to produce a particular enzyme necessary for a metabolic pathway, describe how the absence of that enzyme would affect the cell.

General mechanism of enzyme regulation: /1 b) Prostaglandins are messenger molecules involved in the inflammatory response, as well as th perception of pain. They are synthesized from polyunsaturated fatty acid substrates by an enzyn called cyclo-oxygenase. "Ibuprofen" is the active ingredient in a variety of anti-inflammatory medications such as Motrin® and Advil®. It reduces pain and swelling by binding to a hydrophobic channel in the active site of cyclo-oxygenase, blocking the polyunsaturated fatty acids from binding to the enzyme, and therefore stopping production of prostaglandins.
