Chemiosmosis involves A: the movement of electrons across the cell membrane. B: the movement of hydrogen atoms across a mitochondrial membrane. C: the movement of hydrogen ions across a mitochondrial membrane. D: the movement of glucose through the cell membrane.

According to Abbas, it is reported that one out of every _____ children is born with mitochondrial genetic disorders.

Some athletes believe that dietary carnitine supplements will enhance their ability to perform aerobic exercise. Which statement BEST describes the “scientific” basis of this belief? A: Carnitine is required in the transport of medium and long-chain fatty acids into the mitochondrial matrix, and so increasing the amount of carnitine will increase the rate of transport. B: Carnitine activates carnitine-acyl transferase-1 (CAT-I) thereby increasing the rate of transport of fatty acids into the mitochondrial matrix. C: Carnitine levels in the cytoplasm are reduced when large amounts of fatty acyl carnitine are transported into the mitochondrial matrix. D: Carnitine enhances the activation of fatty acids to fatty acyl-CoA, thereby increasing the rate of their transport into the mitochondrial matrix.
