|
In contrast, the inner membrane are ____
|
|
freely permeable to molecules like ATP, NAD, and coenzyme A
|
|
|
have large channels
|
|
|
impermeable; all molecules and ions require special membrane transporters to gain entrance to the matrix.
|
|
|
None of the above
|
Explanation:
Detailed explanation-1: -The inner mitochondrial membrane contains abundant transport proteins responsible for establishing a proton gradient between the intermembrane space and the matrix.
Detailed explanation-2: -As the high-energy electrons are transported along the chains, some of their energy is captured. This energy is used to pump hydrogen ions(from NADH and FADH2) across the inner membrane, from the matrix into the intermembrane space.
