(a(i))[2]
Suggest and explain why the inner membrane of a mitochondrion does not burst when the organelle is placed in pure water.
(a(ii))[3]
Name three molecules, excluding coenzymes, that are present in the mitochondrial matrix and state how each functions in aerobic respiration.
(a(iii))[1]
Suggest why the inner membrane contains a very high proportion of the molecule cardiolipin.
(b(i))[4]
Explain how hydrogen atoms from reduced NAD and reduced FAD produce a membrane potential across the inner mitochondrial membrane during oxidative phosphorylation.
(b(ii))[2]
Suggest and explain how $P_i$ is carried across the inner membrane of the mitochondrion into the matrix.
(b(iii))[2]
Suggest the benefits of coupling ATP transport with ADP transport across the inner membrane of the mitochondrion.
