Why do molecules of normal haemoglobin not attract each other?
Seems that nobody managed to answer this question in the recent A Level Chemistry paper
Some people suggested that we will perish if that happened, others said Cambridge is trying to make them lose marks. The best answer would be the universal "I don't know"
I thought a more correct from someone was because they are no longer reacting groups hence 1 haemoglobin = 2a and 2b chains. All groups are used up in interacting with one another and hence each haemoglobin can only act as an individual molecule instead of attracting
Sounds quite logical. I wonder if it is similar to the one in Cambridge's answer sheet
