1.	Look at the following experiment. Answer the questions.Testing for prouduction of heat and CO2 under anaerobic respiration a) What is the aim of the experiment?b) Which agent is used to find the presence of oxygen? What changes do you observe when oxygen is present in Glucose solution?c) Why is liquid paraffin poured on glucose solution?d) Which gas is released during the experiment? How can you prove it?
Answer» a) The aim of the experiment is CO₂ is released during anaerobic respiration. b) To find the presence of oxygen diazine green (Janus Green B) solution is used. The blue diazine green solution turns pink when oxygen is present in the glucose solution. c) By pouring liquid paraffin on glucose solution, the supply of oxygen from the air can be cut off. d) Carbon dioxide is released. The released CO₂ passes into lime water it turns milky.
