Which of the following is TRUE about cytochrome c protein? O As a part of the ETC chain, it changes conformation to allow H+ ions to flow out of the matrix. O It is found on the surface of the inner mitochondrial membrane and, therefore, contains start-transfer and/or stop-transfer sequences. With assistance from Bax, it can move out of the mitochondria and into the cytosol. It is considered a symporter because it is involved in electron transport. It is able to puncture holes in the plasma membrane to initiate apoptosis.
