This is the outer membrane of the mitochondria. This is the inner membrane of the mitochondria. Along the inner membrane, we have these proteins known as cytochrome C, which are shown in red and on the outer membrane of the mitochondria. In healthy cells, we have a special type of protein known as BCL Two. Now, BCL Two, what it does is it basically inhibits the process of apoptosis from actually taking place. But if the cell is damaged in some way or form, what happens is another type of protein is produced and released and this protein is known as Bax.
