Assertion A: Electron transport chain (ETC) and ATP synthesizing system are located on the inner mitochondrial membrane.
Reason R: The inner surface of the inner mitochondrial membrane possess phosphorylating subunits.

Show Hint

Inner Mitochondrial Membrane = Site of ETC complexes + ATP Synthase ($F_0F_1$ particles).
$F_1$ particle projects into the matrix and contains catalytic sites for ADP + $\text{P}_i \to$ ATP.
