A. An experience or period in the author’s life.
Explanation:
A memoir is a story about an experience in someones life, but it has to be factual. A memoir can not be based on fiction, it has to be real and nonfictional.
Memoirs are usually told in first person, as it is recounting the occurrences that happened in ones life. It is different from an autobiography, as autobiographies usually focus on the whole lifespan of a person, while a memoir focuses on one topic or event that happened.
Memoirs also usually focus on personal growth throughout the writing, are truthful and keep track of the persons goals and influences.
Hydrogen would be the answer to this.
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.
