A respiratory protein from a marine invertebrate molecule is a quaternary structure consisting of two alpha (α\alphaα) chains and two beta (β\betaβ) chains.
The number of amino acids in each of the β\betaβ chains is 5.517%5.517\%5.517% greater than in each of the α\alphaα chains. Each α\alphaα chain contains 145145145 amino acids.
Calculate the total number of amino acids in this protein molecule. Give your answer to the nearest whole number.
Practise AQA A Level Biology Proteins with exam-style questions for A Level Biology. 22 questions covering General properties of proteins and Many proteins are enzymes, matched to the AQA A Level Biology (7402) specification and written in Paper 1, Paper 2 and Paper 3 style. Every question includes a full worked solution and mark scheme, so you can see where marks are awarded rather than just whether you got the answer right.
