Question

Why hydrogen and electron carriers are embedded in the innner mitochondrial membrane?

Answer 1

the whole point the carriers is to form an electrochemical gradient across a membrane. they need to pump protons from one side to another side of the membrane. the membrane will keep the pumped protons separate, and prevent them from flowing back to the other side. this creates a gradient, which can be used to make ATP.
