Question

A patient has had a serious accident and lost a lot of blood. In an attempt to replenish body fluids, distilled water (100 % pure water) is transferred directly into one of his veins. What will most probably happen? (The concentration of salt in your cells is 0.9%) It will have no unfavorable effect as long as the water is free of viruses and bacteria. The patient's red blood cells will shrivel up because the fluid is hypotonic compared to the cells. The patient's red blood cells will swell and burst because the fluid is hypotonic to the cells. The patient's red blood cells will shrivel up because the fluid is hypertonic compared to the cells. The patient will have no visible effect as the water will hydrate the cells and keep them healthy

Answer 1

Ans1) The patient 's red blood cells will swell and burst because the fluid is hypotonic as compared to cell.

Explaination:100% pure water administerd into patient's vein is hypotonic as compare to body's cell osmolarity. So water enters into red blood cell by endosmosis and results im swelling and bursting of RBCs .

Ans2)Glycolysis;Pyruvate oxidation (transition reaction); citric acid cycle; ETC

Explaination:

Correct order of sequences in cellular respiration :

1)Glycolysis:Oxidation of glucose into 2 pyruvate molecules.

2)pyruvate oxidation :-Pyruvate oxidised to acetyl coA which enters into citric acid cycle.

3)Citric acid cycle :8 step long aerobic process in which oxidation of acetyl coA occurs and release of two CO2 molecules alongwith synthesis of FADH2,NADH and substrate level GTP.

4)Electron transport chain:-last step of cellukar respiration where NADH and FADH2 synthesized during glycolysis and citric acid cycle are oxidised and transfer electron to final electron acceptor ie, O2 and reduced it to H2O.
