Kidney secretes an enzyme, which changes plasma protein angiotensinogen into angiotensin. The enzyme is Correct Answer Renin

The correct answer is Option 1, i.e Renin.

  • Renin is an enzyme that is secreted into the blood from specialized cells encircling the arterioles at the entrance to the glomeruli of the kidneys.
  • Renin catalyzes the conversion of a plasma protein called angiotensinogen into a decapeptide (consisting of 10 amino acids) called angiotensin I.
  • Nitrogenase is an enzyme that helps in catalyzing nitrogen fixation. Nitrogen fixation is the reduction of Nitrogen to Ammonia.

A kidney can be taken safely from a living person, and can save the life of a dying patient. Given that the demand for kidney transplants exceeds the supply of donated kidneys, the law in the India that forbids people to sell one of their kidneys should be abolished, because this would result in a greater number of successful kidney transplants. People are worried that it would involve rich patients exploiting poor potential donors. But selling one's kidney to support one's family is not very much different from supporting one's family by working in a dangerous occupation. Some patients have bought kidneys and received transplants in other countries, where the risks to their life from such operations can be great. Select an assumption supporting the above argument from following options.
Which enzyme should be present for the conversion of angiotensinogen to angiotensin I?
_________ is the enzyme that converts Angiotensinogen to Angiotensin I.
Phytase, an enzyme produced by Aspergillus niger can be adsorbed on microcrystalline cellulose powder (MCCP). The adsorption follows a Langmuir isotherm and the maximum concentration of the protein that can be obtained on the adsorbent is 70 mg cm-1. At a concentration of 50 mg L-1 of protein in the solution, the concentration of protein on the adsorbent reaches 35 mg cm-1. It is desired to recover 90% of the protein from 1.5 liter of the cell free culture filtrate containing 220 mg L-1 protein by addition of MCCP to the solution. The concentration of the protein adsorbed on the solid at equilibrium will be:

Directions : In each of the following questions a statement is given, followed by two conclusions. Give answer :

Statements : About 50 per cent of the animal by-products - hair, skin, horns etc. is edible protein. American chemists have developed a method of isolating 45 per cent of this protein. They used an enzyme developed in Japan to break down soya protein.

Conclusions :
I. Americans have not been able to develop enzymes.
II. Animal by-products protein has the same composition as soya protein.
