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

Question

Quizplus · Accepted Answer

Mitochondrial DNA is responsible for coding proteins involved in the electron transport chain and ATP synthase. Both of these processes are involved in the generation of ATP, which is primarily done in muscle cells. Therefore, mutations in mitochondrial genes would most affect the process of generating ATP in muscle cells.
