Although the Outer Mitochondrial Membrane Is Permeable to All Small

question 34

Essay

Although the outer mitochondrial membrane is permeable to all small molecules, the inner mitochondrial membrane is essentially impermeable in the absence of specific transport proteins.Consider this information and what you have learned about the citric acid cycle to address the following questions.
A.The ATP generated by oxidative respiration is used throughout the cell.The majority of ATP production occurs in the mitochondrial matrix.How do you think ATP is made accessible to enzymes in the cytosol and other organelles?
B.If the inner mitochondrial membrane were rendered as permeable as the outer membrane, how would that affect oxidative phosphorylation? Which specific processes would stop and which remain?
C.Present two types of benefits derived from separating the reactions of glycolysis in the cytosol from those that occur during the citric acid cycle in the mitochondrion.
