Question:
Assertion (A): Influx of ions into inner space of cells is an active process.
Reason (R): Ions are available for free exchange in free space.
Assertion (A): Influx of ions into inner space of cells is an active process.
Reason (R): Ions are available for free exchange in free space.
Reason (R): Ions are available for free exchange in free space.
Show Hint
Distinguish between the mere presence of ions and the energy-dependent mechanisms required to move them, crucial for cellular function.

- A and R are correct. R is the correct explanation of A
- A and R are correct. R is not the correct explanation of A
- A is correct but R is incorrect
- A is incorrect but R is correct
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Assessing the validity of the assertion and the relevance of the reason.
The assertion that ion influx is active is correct; it requires energy to move ions against a concentration gradient.
The reason provided discusses the availability of ions for exchange, which is true but does not explain why energy is needed for their movement into the cell.
