Ayoung girl was born with a patch of soft fur that ran from the base of her neck to her tailbone. she did not display any other symptoms of disease, and results of her karyotype seemed normal. no one on either her mother or father's side of the family had ever been born with this oddity. her concerned mother's side asked a doctor if her daughter would have children that were similarly furry. the doctor told her that while he couldn't be 100% certain, he suspected that this characteristic was the result of

The doctor suspected that this characteristic was the result of a somatic mutation that happened in the developing embryo, but probably wouldn't affect the daughter's egg cells.

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.
