Based on the nature of proton gradient, (A) is false, but (R) is true.
<h3>What is a proton gradient?</h3>
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.

The function of chemical substances such as histamine and leukotrienes would be to stimulate inflammation. Leukotrienes is an example of eicosanoids which play a key role in the pathogenesis of inflammation. They are synthesized in the leucocytes from arachidonic acid via the actions of 5-lipoxygenase. The release of histamine serves as an important part of the body's immune response; when the body comes into contact with an allergen, such as pollen or animal dander, histamine is released by the body to the site of contact and triggers inflammation.
