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.
In the light of the above statements, choose the most appropriate answer from the options given below
Assertion A: Location of ETC and ATP Synthesis
Assertion A states that the Electron Transport Chain (ETC) and the ATP synthesizing system are located on the inner mitochondrial membrane. This is correct. The proteins of the ETC and the ATP synthase enzyme complex are embedded within this membrane.
Reason R: Phosphorylating Subunits on Inner Membrane
Reason R states that the inner surface of the inner mitochondrial membrane possesses phosphorylating subunits. This is also correct. The ATP synthase complex, responsible for ATP synthesis (phosphorylation), is attached to the inner mitochondrial membrane, with its catalytic part facing the mitochondrial matrix.
Relationship Between Assertion and Reason
The presence of the ATP synthesizing machinery (phosphorylating subunits) on the inner mitochondrial membrane, along with the ETC, directly explains how ATP is synthesized during cellular respiration. Therefore, Reason R provides a correct explanation for Assertion A.
Conclusion
Both Assertion A and Reason R are correct, and Reason R is the correct explanation for Assertion A.
