NEET · Biology · STD 11 - 12. Respiration in plants

Given below are two statements: Statement \(I\): Mitochondria and chloroplasts both double membranes bound organelles. Statement \(II\): Inner membrane of mitochondria is relatively less permeable, as compared chloroplast. In the light of the above statements, choose the mis appropriate answer from the options given below:

A Both Statement \(I\) and Statement \(II\) are incorrect.
B Statement \(I\) is correct but Statement \(II\) is incorrect.
C Statement \(I\) is incorrect but Statement \(II\) is correct.
D Both Statement \(I\) and Statement \(II\) are correct.

Verified Solution

Answer & Solution

Correct Answer

(B) Statement \(I\) is correct but Statement \(II\) is incorrect.

Step-by-step Solution

Detailed explanation

Both mitochondria and chloroplasts are double membrane bound cell organelles. Transport of ions occurs across the inner membrane of mitochondria. The inner membrane of chloroplast is impermeable to ions and metabolites. Therefore, it is said that inner membrane of mitochondria is relatively more permeable to that of chloroplast.

Apply the relevant identity from the chapter and substitute the values established in the previous step, keeping the original constraint in view.

Use the simplified expression to isolate the unknown, then plug the result back into the question setup to confirm the working is internally consistent.

Cross-check against a boundary or limiting case. Both the dimensional balance and the qualitative behaviour at the extreme should agree with the candidate answer.

Combine the steps above to identify the correct option. The remaining choices each fail at least one of the consistency, dimensional, or boundary checks.
