You are required to take blood from a patient and keep it in a test tube for analysis of blood corpuscles and plasma. You are also provided with the following four types of test tubes. Which of them you will not use for the purpose?
Clotting of collected blood can be prevented by :
- coating test tubes with silicon (which produces non-wettable surface similar in its smoothness to endothelial lining of blood vessels)
- adding chelating agents (includes trisodium citrate, sodium oxalate and sodium EDTA) which remove calcium which is important for blood coagulation, and prevent blood clotting. Hence test tube containing calcium carbonate cannot be used.
- adding heparin, most powerful anticoagulant which acts indirectly by activating plasma antithrombin III. Heparin is effective both in vivo and in vitro.

R.Q. is more than one when the substrate is
R.Q. or Respiratory Quotient is the ratio of volume of carbon dioxide released to the oxygen absorbed to produce energy. R.Q. value of organic acids is greater than one because they already have a good amount of oxygen in their molecule that can be oxidised which decreases the requirement of external O2. So, correct the answer is 'Organic acid'.
