Describe the background and basic issue of designer babies

    The  first designer baby was created in the U.S. in 2000. Doctors used screening techniques to test the embryos of Lisa and Jack Nash. They chose the embryos that would be an exact cell match to their daughter Molly. Molly suffers from a genetic disorder called Fanconi Anemia which causes bone marrow deficiency. The embryo selected did not carry the disease and was a perfect tissue match. As a result, Adam Nash was born in August after Mrs. Nash underwent four IVF cycles. Stem cells were collected from his umbilical cord to be donated and used to replace Molly's bone marrow. (Baby created to save older sister)Since the creation of Adam, many more couples have created their own designer baby to save their sick child or prevent their offspring from inheriting a certain genetic disease. 

Digestion because it removes waste

Atp is is our little "pocket" of energy. of course, if you have too little, then it means you have too little energy, and you'll pass out. the way to not have enough, is to have no energy sources (glucose, fats, proteins). you can't have too many atp molecules. cycles like the krebs cycle produce it, but if you have too much of any substrate (or too little for that matter), the cycle stops and atp is no longer made (it stops until substrate levels are such that the process can go on). in any case, this is unlikely since atp is constantly hydrolyzed and remade, even while you're asleep. you won't have too much. if you have zero, you are dead or dying.
