Q. What is the sequence of events of protein transport into the mitochondrial matrix?
a
Receptor attaches mitochondrial targeting N-term sequence – peptide is transferred to TOM – peptide is pumped through TOM into TIM – peptide is released into the matrix where chaperones assist protein folding.
b
Receptor attaches mitochondrial targeting C-term sequence – peptide is transferred to TOM – pumped through TOM into TIM – peptide is released into the matrix where chaperones assist protein folding
c
Receptor attaches mitochondrial targeting N-term sequence – peptide transferred to TIM – pumped through TIM into TOM – peptide is released into the matrix where chaperones assist protein folding.
d
Receptor attaches mitochondrial targeting C-term sequence – peptide transferred to TIM – pumped through TIM into TOM – peptide is released into the matrix where chaperones assist protein folding.
