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.

Rudik [331]

Answer:

requires that mitochondrial ATP synthesis and electron flow through the respiratory chain be obligately coupled.

Explanation:

The chemosmotic model was a concept formulated by Peter Mitchell, who stated that during the phases of electron transport in the respiratory chain, an intense release of energy occurs. This released energy allows hydrogen ions to be transported from within the mitochondrial matrix to the intercellular medium. The result of all of this is the occurrence of a chemosmotic gradient. However, when interpreting what occurs in the chemosmotic model, we can see that this model requires that the mitochondrial synthesis of ATP and the flow of electrons through the respiratory chain must be coupled.
