lana [24]
Pompe is a disease in which u have a defect in the lysosome (an organelle found in every eukaryotic cell). The gene should be making a certain enzyme but it doesn't. This causes things to build up in cells that shouldn't be there. This type if disease is progressive and can be fatal. The treatment for this disease is very expensive. A person would need enzyme replacement therapy...which is not cheap. It will drastically affect a person's life. One can have progressive muscle weakness (where they require a walker or wheel chair), respiratory problems (where a breathing tube might be needed) , and heart defects.

These bacteria can tolerate extreme condition like hot temperature called thermophilic conditions. These thermophiles can grow at higher temperature conditions than the eukaryotes.

The thermophiles are non-phototrophic organism as they do not utilize the light energy to produce energy as phototrophic organisms does.
