umka2103 [35]

Answer: The answer is D - Intramembrane space in mitochondria; high

Explanation:

Mitochondria is an organelle in the cell, it is known as the power House of the cell because of its role in the storage and production of energy. During electron transport chain the proton pumps generate a proton gradient which is stored in form of energy.

During proton pumping and electron transfer the electrons are passed down the chain from the matrix to the inter membrane of the mitochondria. The electrons move from higher concentration of level to lower energy level. Some of these are used to pump Hydrogen ions (H+), moving them out of the matrix into the inter membrane space.

The Intramembrane space of the mitochondria therefore has a a high concentration of Hydrogen ions (H+).

I hope this helps.
