    In mitochondria, protons accumulate in the [AIPMT (M) 2011]

    A) outer membrane

    B) inner membrane

    C) inter membrane space

    D) matrix   

    Correct Answer: B

    Solution :

    [B] During the passage of two electrons from one an- electron carrier (NADH) to another on ETC, enough energy is liberated that pumps out three pairs of protons \[({{H}^{+}})\] from matrix, (inner chamber) to outer chamber (inter membrane space) of mitochondria. The accumulation of protons in inter membrane space results their higher concentration than in the matrix creating a proton gradient \[(\Delta pH)\] and electric potential \[(\Delta \psi )\] across the membrane.
