, lives in New Delhi. I think it must be TAJ MAHAL.because the construction price in 1632 was 32 million rupees. at that time india was super power in world. so if you compare 32millions rupees with today's rupees then taj must be most expensive.
The carbonic anhydrases (or carbonate dehydratases) form a family of enzymes that catalyze the rapid interconversion of carbon dioxide and water to bicarbonate and protons (or vice versa), a reversible reaction that occurs relatively slowly in the absence of a catalyst.
Carbonic anhydrase inhibitors. A drug may be classified by the chemical type of the active ingredient or by the way it is used to treat a particular condition. Each drug can be classified into one or more drug classes. Carbonic anhydrase inhibitors cause increased excretion of bicarbonate with accompanying sodium, potassium and water, resulting in an increased flow of alkaline urine. They inhibit transport of bicarbonate into the interstitium from the proximal convoluted tubule.
