Cardiolipin present in inner mitochondrial membrane plays a role in ___________(a) Formation of the respiratory mechanisms(b) Activation of proteins involved in Glycolysis(c) Activation of proteins involved in electron oxidation(d) Activation of proteinsThe question was asked during an interview for a job.My question is based upon Mitochondrial Structure and Function topic in chapter Mitochondrial Structure and Function of Cell Biology

Answer»

The CORRECT ANSWER is (c) Activation of proteins involved in electron oxidation

Best explanation: The inner membrane of MITOCHONDRIA is virtually DEVOID of cholesterol and rich in unusual phospholipid and cardiolipins, which is the characteristics of bacterial membrane, from which the inner MITOCHONDRIAL membrane has presumable evolved. Cardiolipin plays a role in facilitating the activity of several large protein complexes involved in lector transport and ATP synthesis.
