Cells lining the tubule have numerous mitochondria to produce enough energy (ATP) for active transport to take place.he distal convoluted tubule has a different structure and function to that of the proximal convoluted tubule.

Obesity is officially classified as a disease under the World Health Organisation's International Classification of Diseases. In a report published in 2000, the WHO said: Obesity is a chronic disease, prevalent in both developed and developing countries, and affecting children as well as adults.
A reason the AMA decided in favor of obesity as a disease is that it will decrease the stigma of obesity that comes from the widespread thought that it is just the outcome of excessive eating and not enough exercise.Doctors say some people do not have complete control of their weight.hose who did not agree with the change of classification cited that making obesity a disease would categorize one-third of Americans as being sick and may lead to more medication and surgeries that are expensive, instead of lifestyle changes.
