Question:
Given below are two statements.
Statement I - Protons are channeled from inner chamber of mitochondria into outer chamber by \(\text{F}_{0}\) part of oxysome during ETS.
Statement II - Cytochrome C is a small, iron containing protein tightly associated with inner membrane.
In the light of above statements, select the correct option given below:

Statement II - Cytochrome C is a small, iron containing protein tightly associated with inner membrane.
In the light of above statements, select the correct option given below:
Show Hint
Complexes pump protons out of the matrix, F0 channels them back, and cytochrome c is only loosely attached.
Updated On: Nov 12, 2026
- Both statement I and statement II are correct
- Both statement I and statement II are incorrect.
- Statement I is correct but statement II is incorrect
- Statement I is incorrect but statement II is correct.
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Understanding the Concept
In the electron transport system (ETS), electron carriers pump protons from the matrix to the outer chamber.
The protons then flow back through the \(\text{F}_{0}\) channel of the oxysome, and \(\text{F}_{1}\) makes ATP.
Step 2: Statement I
It says \(\text{F}_{0}\) channels protons from the inner chamber to the outer chamber. This is false, because the \(\text{F}_{0}\) channel carries protons from the outer chamber back into the matrix.
Step 3: Statement II
Cytochrome c is a small iron-containing protein, but it is only loosely held on the outer face of the inner membrane as a mobile carrier between complex III and complex IV. It is not tightly bound, so this statement is also false.
Final Answer:
Both statements are incorrect, option (B). \[ \boxed{\text{(B) }\text{Both statement I and statement II are incorrect}} \]
