Based on the nature of proton gradient, (A) is false, but (R) is true.

What is a proton gradient?

A proton gradient is a gradient that exists due to difference in proton concentration between the inner and outer mitochondrial matrix.

An assertion is a statement or claim stating a given position.

  • Assertion (A): A proton gradient cannot be established in the mitochondria.
  • Reason (R): Hydrogen molecules are pumped out of an internal space (the matrix) in the mitochondria.

The assertion, A, is false because a proton gradient is established in the mitochondria due to the function of the proton pump which pumps out protons from the inner mitochondrial matrix to the outer membrane.

The reason, R is true as hydrogen molecules are pumped out of an internal space (the matrix) in the mitochondria by the proton pump.

Therefore, (A) is false, but (R) is true.
