I have 27 questions on this little article I seemed to answer all the questions but this one. Can some please help me
HERE IS THE ARTICLE;
"Snake venoms are complex brews of poisonous proteins. The venom of the Western Diamondback rattlesnake is rich in enzymes called phospholipases , which break down the phospholipids of the plasma membranes of cells, causing the cells to rupture and die. Cell death blackens the tissue around the bite. In the bloodstream, the phospholipases attack red blood cells, reducing the oxygen-carrying capacity of the blood and causing the victim to become short of breath. Once carried to muscles, phopholipases also attack muscle cell membranes, exposing the complex contractile proteins within the muscle cells to attack by protein-digesting enzymes in the venom. Proteins that strengthen blood vessels also come under attack, and hemorrhaging may result if the vessels rupture. The venom also contains enzymes that attack blood-clotting proteins, making the hemorrhaging more dangerous. When internal bleeding is combined with loss of the oxygen-carrying red blood cells, it is no wonder the victim is short of breath and may go into shock.
Karl was extremely lucky that Mark had brought his cell phone. Trying to hike back to the car would have quickly spread the venom throughout his body, and the added delay would have decreased his chances of survival. Fortunately, Mark was able to get expert advice immediately; keep Karl lying down-since he was suffering from shock-and as immobile as possible until help arrives. Because they had identified the snake, the hospital had the correct antivenin waiting. Antivenin contains proteins that bind to and neutralize the various toxins in the snake venom. The Western Diamondback, with its half-inch-long fangs and large stores of venom, is responsible for more U.S. snakebite deaths than any other species. To keep matters in perspective, however, of the 7000 to 8000 people bitten by poisonous snakes in the United States each year, only 10 to 15 people are killed by the venom. "
NOW HERE IS MY QUESTION--
3. Phospholipases and other digestive enzymes are found in animal (including human) digestive tracts as well as in snake venom. Why do we have phospholipases in our digestive tracts? Since snakes swallow their prey whole, what are two very different roles for the phospholipases and other enzymes in snake venom?
THe answer is no where to be found please helpp
Please help. Thank you
