Mitochondrial DNA is primarily involved in coding for proteins needed for protein complexes of the electron transport chain and ATP synthase. Therefore, mutations in mitochondrial genes would most affect which of the following processes?
A) DNA synthesis in cells of the immune system.
B) The movement of oxygen into erythrocytes.
C) Generation of ATP in muscle cells.
D) The storage of urine in the urinary bladder.
